i dont know how to do this, but i know it has to be done right or it can harm the chicken. a cousin told me that since the quill is like a straw, the blood could possibly run freely through it. not sure if thats true or not.....
Have someone hold the bird and gently pull wing out. Look at the 10 feathers at the tip(should be the longest). Use VERY sharp, strong scissors and cut straight across at half of the feather. If you cut into the blood vessel, immediately grab that feather at the base where it attaches to the muscle and quickly pull it out. This should stop the bleeding. Only clip one wing per bird. Otherwise they will still be able to fly balanced. Note clipping one wing, they still can fly up about 4-6 feet high.
i clipped mine two days ago and it was quite painless for the chicken. I didn't enjoy doing it but I had a houdinie. I watched a few youtube video's to get the idea of how it's done. It literally took me 2-3 minutes and most of that was in catching the silly thing. Hope it goes well for you
I tried clipping one wing on a few of the girls, and 2 wings on the other half... but one of the one-wingers could still get over my 4' high fence. Once she was clipped on both wings, no more escapees. I tend to leave those 10 long feathers at the wing tip alone and cut half off the remaining (or base) of the feathers. I think they look better with the tip feathers.
