I'm not sure where to post this. Indy is one of my younger chickens. When I found him in the nestbox, his legs and wings were straight out in front of and to the sides of him, he only wobbled and couldn't walk, and his abdomen wasn't completely formed. I left him there with his mother thinking that would be best. The next day, he was walking around and looked normal. His mother was completely disinterested (I have a couple of hens who are notoriously bad mothers), so I took him out and put him with two other orphaned chicks a few days older. Indy seemed fine until the wing feathers started coming in--they were growing backwards. As the entire wings formed, they seemed to be completely inverted thus leaving his sides exposed. He has normal feathers some places and next to nothing other places. In the pictures, you can see two other birds younger than Indy, and they're fully feathered, so I think this is it for him. I live in Texas, so winter is mild, but it does get to freezing dome days. Will he need a sweater? If so, where can I find a pattern, and what fabric is best?
