Hi, I have a question about moving my young girls in with my older girls. I have six three yr old hens (two Americanas, two leghorn, a Rhode Island Red and a black ostrolarp) I also have four 8 week old girls (two barred rock, two isa brown). I know there needs to be a certain amount of time that they are separated but still can see each other. My husband built a small coop next to the big coop and put chicken wire around it so the Littles can have their own space and the big girls can see them. They are on their third day in the little coop and my big girls are definitely curious. My question is...how long should they be like this? When would be ok to put them all together?
