Howdy! I have 5 7 week old chicks that I picked up over the weekend (2 Rhode Island Reds, 2 Black Australorps, and a Barred Plymouth Rock). One of my Australorps has very few feathers on her back when she spreads her wings and she seems to pick at her feathers a lot to the point that some are a bit bent. My chicks are still in the brooder for another few days because it has been getting down to the low 40's here at night, and I haven't noticed more than 1 or 2 feathers in the brooder so I don't think she is actively pulling them. On her wings I can see patches of very soft, downy feathers compared to her more adult ones. Is it possible that she just hasn't grown in all her feathers yet, or should i be worried that she is actively having a feather issue? Thanks!
