All my now-13 and 14-week old chicks decided to sleep all together in the 2 floor-level nesting boxes of the coop. They're totally uninterested in the two roosting bars in the coop itself. One of my pullets has been squatting a lot lately, and I just realized if she starts laying soon the nesting boxes are occupied. Will there be a problem if they continue to sleep in the boxes; should I block off one of the two?
Sleeping in nest boxes leads to considerable accumulation of waste in the boxes - which leads to poopy eggs when birds start to lay. It is better to move the birds out of the box and place them on the roost at night so they learn to associate the roost as the place to sleep rather than the box.
