She has lost some more under her wings and on her head. Sorry about the photos, but I just can't get her to keep still. What is the keratin sheathing? First time I've ever heard of it.
Hi!
I have one baby chick, which was from one of my hens and I have her at home. She got a small injury three days ago and I treated with a dab of betadine and a tiny bit of fucidin. She kept pecking at it though, so I put some organic blue food coloring and she pecked it maybe twice a day...
