Hi, I am curious about your chick. Did she improve further? I have a chick that is about 7weeks old, and I have noticed that she/he seems to be a bit weak in the legs. She/he can still walk just fine, however it seems that it may have taken a jump and possibly landed wrong. I can't find anything physically that would prove the injury (no noticle swelling, or anything obvious) However I notice that when lifting the chick up, the toes curl on both feet when I lift it up to examine the legs. It's frustrating because I would love to know how to heal this chick, but don't know where to start. Wouldn't a chick show leg issues right off the bat if it was a nutritional deficiency? I have the whole group on medicated chick food.
