2 of my hens have stopped laying in the laying box and started laying up on an are of the coop's rafters(stupid.. how would chicks get down??) in order to hatch eggs... theyve currently got about 11 up there and theyre taking turns sitting on them for about a total of 6 hours of the day.. they don't sit on them at all at night? Are there any chances of chicks actually hatching with them not constantly sitting on the eggs? Do I need to just get the eggs down?
