My buff orpington likes to steal the other chickens eggs, and sit on them while she lays her own egg. Lately, she has been spending a LOT of time on the nest. like easily 3 or 4 hours. I go out there at like 6;30 and let them out to run around, and then at 10 i go in to check, and she is usually sitting on the nest. She hisses this terrible dinosaur noise at me, but i scooch her around and take out any eggs. Then at like 3 after getting my kid from school, i go back out there and scooch her around and take the other eggs. Today, she was on there all day long. Is it bad for the eggs to be warm so long? is she trying to hatch them? or is it just taking her hours and hours to lay an egg? help!
