We have a BO that started laying at 20 weeks. She laid an egg every day until last week. She hasn't laid one since. Saturday morning our dogs got in the coop and killed one of the other girls, then TS Lee went through, so there was a lot going on last weekend. I have noticed that she's squatting again, and I heard the "egg song" two days ago, but still no egg. Does anyone have any advice?
