Not sure if this is a coop question or not - sorta. I have just had a new coop built on site, it is 8 x 12 and the idea was to split it in two sections in the future. But for now, there is no need to do this. Since I will be culling my chickens down to 8 birds, will they get too cold in this big coop? Should I make them a smaller "doghouse" area inside where they can sleep to keep warm together? Also, After thanksgiving, I will have only 5 pullets left (I am raising some for my out of town sister). The chickens are very young still - only 8-12 weeks old and are still in the garage with a little heat lamp. It is about 50-60 in the garage now. They are sort of sickly and we are hoping they will get well soon so we can have our garage back!
