I have 4 chicks going on 4 weeks old, everyone is healthy, eating, drinking, scratching like normal except maybe one. She seems to do her own thing, like she's on a different time frame. She is growing normally and eats and drinks and of course uses the bathroom. She seems to separate herself a lot and she's not aggressive about food at all, a lot of the time she just stands and stares. I have wondered now for about a week if she can see very well, she appears to high step a little? Any thoughts?
