Luckily I put my chicks in a brooder in DD closet, since she has the biggest one, and that is away from the rest of the house.
I didn't have the coop done before the chicks were ready to go out so we had a temp pen built into the little nook of the house. Three sides were house and wire in the front and top. Woked pretty good although now we are putting vinyl siding on the house and the temp pen had to go. We finished th big coop and the 6 ladies 16 weekers are in there and then I used part of the other to make a shipping crate into a tractor like pen to put the 3 EE, 8 weeks, in and NOW they are living with 10 more little chicks!!!
I really need to get everyone in the same place before winter sets in although I did buy some things to insulate the younger ones crate if I have to. The BR is the ruler of the coop and for some reason doesn't really like the others when we tried to integrate them!!
