I have 3 chicks in my homemade brooder, which is a tub with the top cut out. All the necessities and the chicks seem to be doing well. One of the chicks though, the RIR, is at least a week older than the others. Sometimes I think she may be 2 weeks. She is molting her baby fuzz and getting her big girl feathers and is trying to fly. She is quickly outgrowing the brooder. Problem is that the other 2 arent outgrowing it. I was thinking of moving her to a modified dog crate for the next few weeks, but I am concerned that separating her and the 2 smaller chicks will cause problems in the future when I put them back together. She is definitely the top of the pecking order and the other 2 are so sweet it is amazing. So I am looking for advice on what I should do here? Leave them all together? Move them around? Move them all into the dog crate (worried the little ones wont stay warm enough). Thanks!
