I have four chickens and three nesting boxes. My girls aren't laying yet but have started taking an interest in the nesting boxes. They sleep in them. I've read people say to not let them sleep in the nesting box, but short of sleeping out there with them (no thanks), I can't keep them out of them once they're put up for the night. The perch is right below the boxes, too. Anyway, the overcrowding is three chickens taking claim to one nest. The fourth chicken (my dominant girl) has her own box and one sits unused. They've just started doing this less than a week ago. Even with a flashlight the other night I could only count three in the coop and was looking around the run for a straggler. Then I opened the lid to the nesting box and physically touched three bodies in the one nest to know they were all in the coop. And in the morning when I open the coop and let them out for breakfast it sounds like the Three Stooges inside the coop with all three untangling themselves and getting out of the one nest. Is there anyway to lure them to another nesting box or is this just something they'll have to figure out for themselves? BTW-it's not for warmth sake they're snuggled up together. I'm in Florida and the lows have been in the low 60's this week.
