My Polish have started to lay after their move from their old home to their new home. One hen is laying an egg a day. Awesome! The other hen is also laying an egg a day....she then pokes a small hole into the pointed end. She does not break the inner membrane though. I am not even sure she is doing it. We just have a small hole in one end. I have add extra shavings to the next boxes thinking that if the egg fell and cracked that would fix it. It didn't. I don't know what to do. Any suggestions?
