I have 16 in a 4x8 sq ft space... is this ok? Getting ready to set up the rest of the coop. They have a roost I build and I just also added a bamboo across the back. I still have a heat lamp I can switch on at nights. My younger babies are in a tub with their light on (blue Plymouth rocks). The whole coop is 15x18 and eventually the silkies will be separated out to a 4x 10 area, and my colored egg layers will be in this half where the babies are now (but opened up a bit more so it’ll be 4x 12). Then the rest of the flock will be on the other portion which will be 12x 11.
