Hi y'all, I have ten 16 week old hens of various heavy breeds. Up until recently I had them in a small tractor type chicken coop out on the lawn with a small run. Knowing they needed more room I upgraded to a large coop with 4 nesting boxes and a huge 200 sq/ft run. So my family and I were super stoked about being able to give our chickens all this space to hang out and sleep. The problem? At night all ten of our girls are cramming themselves into two of the nesting boxes to sleep. So five heavy breed chickens literally stacked two high in a 14"x12"x12" nesting box. They sit on their roost intermittently during the day and they are outside most of the day unless its too sunny or warm...and the nights aren't very cold. Is there any way to discourage them from sleeping so many in one nesting box? Is there something i should do to make the rest of the coop more attractive for sleeping? thanks in advance.
