Chick is CONSTANTLY pulling on her/his wing. What do I do?

[The Mother Hen]

I had to place all of my chicks in a box because they keep falling out of the nesting boxes outside. Right now (as I type) there is a chick pulling on its wing... like tugging on it. Could it just be a sign of being crowded or do I need to worry about something else? She/he is getting it's pinfeathers in, so could that be the problem as well? I don't think her/his wing is broken.

It sounds like it's preening? My chicks were constantly messing with their pin feathers as they grew out also. I wouldn't worry unless it draws blood.

Well she would walk around with her wing and fall over, and at first it was funny but then I got concerned. Now she isn't doing it anymore so I guess she was just preening. It was odd though because all of the other chicks stood in place to preen. Thanks for the tip though!
