Our gold cuckoo marans started egg-laying behavior a week or more ago: the submissive squat, the egg song, and she repeatedly goes into the egg box as though she's trying to lay an egg. But despite this behavior for more than a week -- no egg! The white marans we got at the same time started laying 3 weeks ago, and usually gives us an egg every other day. What can be going on with the gold cuckoo marans?? I've even peeked in the egg box and seen her pushing. She's otherwise fine. Good appetite, walking around normally, no problems. What the heck?!
