Hi there. I have 4 RIR that are about 14 weeks old. I have one laying box in their coop. They all 4 try to cram themselves into the 1 box (12"x12") when they sleep. They lay on top of each other. It is quite funny to see. Will they stop this when they start laying eggs? Are they supposed to use it as a bed? There is enough room in the coop itself to sleep (although it isn't overburdoned with size (4x4). They have plenty of room outside to move around. I wanted the coop to just be for sleeping and laying. What do you think?
