I've had my 12 ladies for about 2 months now. They're secondhand, between 7 and 18 months old. Several of them are molting right now. The first week we had them, I found a few eggs on the floor of the coop, some broken some intact. I just figured they were getting the hang of the new coop. I could tell one of them was laid on the perch because there was a yolk smear on the top lip of the nesting box. Since then, most of the eggs have been in the nesting box. But I still occasionally find one that was laid from the perch at night. I rarely find the shell, usually just the yolk smear, so they are cleaning it up themselves. I've only had a few eggs with pecked holes in them, so I don't think egg eating is the issue, just the fact that one silly chook lays at night while roosting. Is this normal? What can I do about it?
