My set up is as follows: 1 long-term coop 2 cat litter nests with ample extra roost space for the Roo and non-broody, non-laying hen 3 hens, 1 Roo. So far that I can tell, I have 2 hens laying. Both would lay their eggs in 1 of the boxes, then 1 of them would brood. When we took some eggs from them, there are now eggs in the second nest being ignored, and in the first nest being brooded. When we'd go outside to check on them, the 2 hens seemed to interchange who was brooding. Do I need to remove the 2nd nest so they'll lay all back in 1 again, or is the 2nd nest for infertile eggs? I don't know why they'd be separating them.
