Hi All, I'm new to the backyard chicken world and I'm raising my first chicks. I got seven Barred Plymouth Rocks. They seem to be very healthy and happy except today I noticed that one of them has started to pluck his/her own feathers out. I've been watching them closely this evening and it looks like the other chicks are not bothering him/her so it does seem to be self inflicted. I've done some reading and the brooder might be getting too small for all seven chicks. My husband is out in the garage right now, making a 2nd brooder to attach to the side of the current brooder. Hopefully that will create enough space until we get the coop built in the next couple of weeks. My question is this....If the addition of space does not help with the plucking and I separate this chick from all the others, will that help or hurt? I don't want the other chicks to start pecking at him/her and I'm concerned about what they'll do if I keep him/her away for too long. Any suggestions? Thanks for any help.
