My BA hen, who will be 2yrs this spring, has for seversl months been laying outside even tho she always sits in the nest box first. I have been trying to catch her in the act so i can better understand what is going on. One forum described a hen who regularly sat on the egg long enough for it to adhere to her rump feathers as it dried and the egg eventually would fall somewhere else. .I was thinking that might be the BA's issue. But today, i finally witnessed the event. I knew she was on the nest and i hung out until she emerged. I had a treat of kale for the girls, and i looked closely at the BA's bottom, no egg , no egg in nest either....suddenly she got a strange look, her neck feathers stood out horizontally, she squatted and....at that same moment as a warm wet egg popped out, the RIR hen attacked her, actually jumped on her back. The BA was so upset she didn't want her treat. So now i wonder if the RIR might be bullying her out of the nest, or if the BA just is somehow unaware of when the egg emerges. The only other members of the flock are 2 pullets. One is laying , and in the same nest with no problem it seems. The RIR, same age as the BA, hasn't begun laying since her molt. Anyone have any insight on these behaviors?
