I have a question related to when to put chicks in the coop. I have 23 3-week old chicks of 3 breeds. In another week, I think they that 23 will crowd the 8' X 2' brooder, although they seem quite active and normal at this point. I have 6 New Hampshire birds that I think are the pullets that look like they will be feathered by the end of this week. And the 4 NH roos maybe close to feathered. My Brown leghorn pullets and some of my Barred Plymouth Rocks are just a bit behind, but at least 3 of my Barred Plymouth Rocks are no where near feathering in fully. Barely have their wing feathers. They seem stuck in terms of feathering, though they are very active, curious and the most friendly.
I should probably ask about their slow feathering, but I figure it might be genetics. My question is whether it would be okay to move some of the birds out to the coop before I move the others. That would give the remaining birds enough room in the brooder and keep them warm enough. I will have a heat lamp in the coop for a while, but the nights will likely get down into the 30s. Am Iikely to cause behavior problems by separating them for a week or two? It might be the 10 NH that would all go out together, leaving the rest behind for awhile. Or, it could be everyone but the 3 little Barred Rocks would go out together...?
UPDATE: So, I found a webpage explaining delayed feathering in some breeds, including Barred Rocks. It is a sex-linked trait, and based on how behind 3 of mine are and what I read, it is going to be quite a while until these birds have feathers! What will happen if I keep them in the brooder (maybe with a few others for warmth) until they become feathered - perhaps separating them for several weeks? Will they reintegrate okay? Is there a certain age by which I should try to get them out with the others?
