this is Nettie, she is 5 weeks old, she's been messing with her feathers. Is she too young to have a nice dust bath in some diotomaciois earth (food grade of course) or could she be too hot? The only one? She is bigger, maybe she's slightly older? and it got cold here and they were inside then in a barn (both under a lamp at about 75f) then came here (inside again over the course of a week though and inside there's also a heater but I monitor the temp and its been between 65-80f) they can get away from the lamps hear but not the heat in the room... She's pulling the feathers from where you see in the pic and behind her wings... Could she just be stressed? Its been a crazy week for her? She's acting like a normal chick, eating, drinking, doing her bird business, I've never seen a chick do this, she's not exceptionally timid and she's not being bullied though I did see one of the other large chicks try and perch on her. There are 6 together in a 3 foot across octagonal brooder. Could she be itchy? She was in a barn for a couple nights, could she have something on her? She just started last night and I don't think its good for her. Please help any advice is appreciated, I'm Hoping to stop it before it gets any worse or the others start. Thanks!!!
