When I had banties, all the hens would lay in one box and all sit on that clutch, peeling off one at a time as the eggs hatched until they were all hatched. That was normally in the early summer/late spring. They didn't lay a lot in the heat of summer, and that may be the case here. If they did lay, they got broody again. And if I went in there to get the eggs, I was in for a fight.
