I have a gorgeous Golden Wyandotte. She's 31 weeks old and hasn't laid yet. She's been squatting for about 8 weeks yet not one egg. She spent a few days practicing in the nesting box early on, but I haven't seen her go in again for weeks. Is she a lost cause? She's very bossy, the leader of the flock yet she hasn't produced. I thought squatting was a good sign, but after all these weeks, maybe not. Any advice?
