Ok, so I have 14 chickens 1 roo and 13 hens, 2 of them are about a year old and laying, and roosting normally, and the other 12 are only 12-16 weeks old. The 12 younger ones are ALL sleeping in 3 of their nest boxes. Their coop is an A frame and we have it set up so their boxes line the floor along each side then their roosts are in the middle area. They just all pile ontop of each other and sleep they havnt showed any interest in the roost. I try to push them out of the boxes and they just all pile back in. What Im wondering is should I stop the behavior now or will they grow out of it? Or does it even matter?
