I have a hen that is still laying eggs once a day but she won’t leave the nest. She’ll sit on any egg even a wooden egg after I take her egg. I’ll take her out of the nesting box and I’ll put her in the pen. Within 10 minutes she’s back in the nesting box purring as if laying an egg. Any suggestions? I don’t know what to do. Is she egg binding or is she brooding? She’s been like this for a week.
