If it is alive before peeling, it needs to be put to death; If it is dead, the body should be examined as follows: whether the feathers are complete and whether the body is corrupt. It is very important to check whether the body is corrupt. The inspection method is: pull the feathers on cheeks, abdomen and crops hard, and use them only if they don't fall off.
Some chickens were killed by bullets, and wounds and other places often shed blood or dirty things to pollute their feathers. You can wash it with a brush dipped in water or detergent, then wipe off the water and sprinkle gypsum powder or talcum powder on the washed place. After the feathers are dried, gypsum powder can be brushed off to make them fluffy. If it is not completely dried once, it can be repeated again.
The skinning methods of chicken specimens are basically the same (except for special species). Now, taking domestic pigeons as an example, the description is as follows:
Put the chicken on the table, chest out and head to the left. Separate the feathers of the chest to expose the bare hair area, cut it from the depression in front of the chest keel, and cut it straight along the skin to the center of the chest keel. The length of the opening should be slightly larger than the breast width of the chicken. Beginners' openings can be enlarged appropriately, but not too large. It is difficult to deal with in the later suture and plastic surgery. The front end of the opening should be exposed to the neck, and then peeled off along the skin and muscles of the chicken breast with a scalpel, reaching the armpits on both sides of the chest. In the process of peeling, you should always sprinkle some gypsum powder on the inner side of skin and muscles to prevent feathers from being polluted by blood and fat.
Forward, use a scalpel to separate the crop from the skin and expose the neck. Hold the chicken's head with your hands, bend the chicken's neck to the abdomen, and then cut the chicken's neck, esophagus and trachea together with scissors near the chest. At this time, we should pay attention to: ① The neck is completely cut from the skin, and do not cut the neck skin. (2) If there are blood spots, gypsum powder should be sprinkled in time to avoid blood spots polluting the skin. (3) It is best not to stubble. If the crop is accidentally broken, you should pick up the chicken in time and peel off the food in the crop to prevent the food from polluting the feathers.
Turn the chicken over so that its back is up, then turn its head and neck over, and peel off the chicken's back along the chicken skin to reveal its shoulders.
Continue to peel off the humerus on both wings. Remove the muscles from the humerus and separate the humerus from the bird at the shoulder joint.
Continue to peel back the waist. When peeling the waist, the back and abdomen should be done at the same time. When exposing the leg, peel the skin all the way to the joint between the tarsometatarsal bones, remove the muscles on the tibia, cut at the joint at the upper end of the tibia, and separate the tibia from the chicken.
When the tail is peeled off, the rectal floor is cut with a knife when the cloacal hole is peeled off; When peeling the tail, the tail fat should be completely separated from the skin and cut off at the end of the tail heald with scissors. After incision, the endodermis is V-shaped. Be careful not to cut off the shaft root of the tail feather to prevent the tail feather from falling off. At this point, the body muscles and skin have been completely separated.
Then peel the skin off the wings, pull out the humerus and peel it directly to the ulna. When you peel the ulna, because the root of the wing feather shaft is firmly born on the ulna, you should completely separate the wing skin from the ulna with your fingers close to the root of the feather shaft until you peel the wrist, and then remove all the muscles on the ulna and radius.
When making specimens of spreading wings, the wings cannot be peeled off by the above method. Because the feather roots on the ulna are separated from the ulna, when the wings are spread, the flying feathers will droop and cannot be opened because there is no support. Therefore, when making specimens of spreading wings, the skin should be cut inside the ulna to remove the muscles attached to the ulna and radius, and then sutured along the skin incision.
The wings are peeled off, and then the head is peeled off. Pull the neck first, so that the skin of the neck turns over to the head and gradually peels off, exposing the occipital bone. At this time, a taupe ear canal will appear on both sides of the occipital bone. Cut with a scalpel close to the base of the ear canal, or pull it out along the base of the ear canal with pointed tweezers. If you peel it forward, there will be dark parts on both sides, which are the chicken's eyeballs. Use a scalpel to cut the marginal membrane of eyelid, use tweezers to take out the eyeball (be careful not to cut the eyeball and eyelid), and observe the color of iris at the same time when installing the artificial eye to color accordingly.
Around the occipital hole, use scissors to enlarge the occipital hole and cut off the neck. At the same time, the muscles were cut along the medial sides of the mandible, the chicken tongue was pulled out and the head muscles were removed. Use tweezers to extend into the cranial cavity from the enlarged occipital hole; Clamp the meninges and take out the brain. In this way, the whole stripping process is completed.
Some chickens. Such as woodpeckers, ducks and so on. The head is big and the neck is thin, so that the bones on the head cannot be turned out from the skin of the neck. First cut off the neck, then cut a small mouth along the pillow from the outside (the size depends on the size of the chicken head), dig out the skull from the small mouth, dig out the ear canal, remove the eyeball muscles, etc. After removing the rot and installing the artificial eye, sew a small mouth.
After peeling the chicken, check it again to remove the muscles and fat attached to the skin. The gypsum powder scattered on the skin during peeling should be brushed off, and the skin accidentally cut during peeling should be stitched (from the inside).
After the chicken is skinned, the inside of the skin must be treated immediately. In the process of antiseptic treatment, the feathered side will gradually turn back to the body surface and restore its original shape. Anti-corrosion and repair steps are as follows:
First, apply arsenic trioxide antiseptic cream (arsenic trioxide antiseptic cream) to the eye socket, cranial cavity and mandible, fill the eye socket with two cotton balls as big as the eyeball, install the artificial eye in a proper position, then apply the antiseptic cream to the inside of the neck skin with a brush, and gradually turn the head over (be careful not to pull hard to avoid the neck feathers falling off).
Secondly, apply antiseptic cream to the tibia of both feet, and wrap cotton on the tibia, big and small. The same as the muscles on the original calf; At the same time, the skin can be completely restored to its original state after all the antiseptic ointment is coated on the inside of the calf, tail and wings.
(6) Filling chicken specimens
There are many ways to fill chicken specimens. The simple, easy-to-master and effective methods are introduced as follows:
1. Fabrication and installation of brackets
Before filling, a bracket should be installed in the chicken to support the chicken. The bracket is made of lead wire, and the thickness of the lead wire depends on the size of the chicken. Take two sections of lead wire, one of which is 1.3 times the length from the beak to the toe (based on when the chicken is supine and straight), and the other is 3 ~ 6 cm longer than the former. Twist it in the following order and bend it to make a bracket (the twisted part should be tightened). When screwing, 1 3 should be aligned, and the length from the shorter 4 to the screwing point should be based on the length from the beak to the front end of the original keel. A ~ A' ′ is 1/2 of the width of chicken breast, and A ~ B and a ′ ~ b ′ are two-thirds of the height of chicken breast.
After making the bracket, cut the four ends into sharp points with pliers, and wrap it in cotton about 0 ~ 4, which is slightly smaller than the original neck. Insert both ends of 1 and 3 respectively between the tibia and tarsometatarsal joint of both feet from the rear side, and pass through the soles of feet along the heel direction. At the same time, insert both ends into the tail and pass through the center of the ventral surface of the tail to support the tail feather.
Try to move the lead wires at both ends of 1, 2 and 3 backward, so that the 4 ends penetrate into the neck, insert the tip of the upper beak of the chicken from the cranial cavity, and bend the 4 ends to the abdomen of the chicken a little, so that the head of the chicken will not shake. Finally, adjust the position of the lead wire bracket to make the chicken body conform to the length before peeling, and the center point of lead wire winding (that is, the original zero point) is located at the front end of the original chicken keel.
Most of the artificial eyes sold in the market are transparent glass with only one black spot (pupil) of different sizes in the middle. At this time, according to the color of the chicken iris, paint the back of the artificial eye with oil painting color (or advertising color), and then melt a little paraffin to cover the color. If the artificial eye is not installed during the anti-corrosion process, it can also be installed during the plastic surgery process. The installation method is similar to the fastening button.
2. Filling of bird specimens
Put the bird skin with a bracket on the table. Fill in the filler (cotton, bamboo, etc.) first. Under the bracket (between the bracket and the back skin), followed by the tail, waist and back. When filling the back, it is necessary to keep the filler flat, and the filling thickness is about 1/3 of the chest height (living body), so that the bird specimen made will not show traces of uneven back and lead wire support. When filling the back, you should also pay attention to the filling near the neck. If there is less filling, there will be depressions, and if there is more filling, it will be raised, which will affect the beauty of the specimen.
A long piece of cotton should be used in the neck and sent directly to the bird's jaw with tweezers. One is to make the bird's neck into an oval shape, and the other is to fill the gaps in the tongue and muscles of the mandible, and fill some fillers on both sides of the neck to replace the trachea. After filling the back and neck, pull out the bird's humerus and put it above the bracket (near the bird's abdomen). The humerus is approximately parallel to the central axis of the stent. Turn the bird over after putting it, and observe whether the wings are in place and whether the padding on the back is flat.
Then put the bird's belly up, press a heavy object on the humerus to prevent the wings from moving, and tilt the bird's legs slightly upward, and then continue to fill the abdomen and tail according to the bird's living conditions. Fill a little more when you are alive than the original bird to prevent the bird's skin from shrinking after it dries. At the same time, we should pay attention to filling some fillers on both sides of the bird's calf to make the two sides of the bird plump.
The general principle of filling is to make the specimen conform to the original ecology of birds, so it is best to observe more before making bird specimens, measure the positions of various parts of birds, such as neck length, body length, wing length and the length between wings and tails, and make records for reference. After filling, the opening of the bird body should be stitched, and the filling work is completed.
Brother, this answer is satisfactory. Hehe, I'm your brother Yang.
