When my pullets got close to laying age, I made sure they had a fake egg in the nest box so they would know to lay there. But they didn't want to since older hens who they are afraid of lay there. So one of mine chose a spot on top of a bale of hay. It wasn't a bad spot so we put a nest box there for them. The next day, my most mature pullet was up in the nest box, panting like she was close to laying the egg. But then she hopped down, walked around for a bit, then squatted like she was going to poop and laid the egg on the ground! She did the same thing the next day. Why is this, and how can I can I stop it?
