I have an Easter egger that up until 3 days ago was a normal layer, now she won't leave he nesting box, the only out of the ordinary thing that has happened is we mowed the lawn near our coop, I thought she may be egg bound and as far as I can feel there's nothing in there, if I take her out of the box she will eat/drink/preen normally but after a few min she runs right back in she is also still pooping and I don't see any worms, I've also notices the other hens have been pecking at her more than usual...help!!
