I found my hen, who has been a great egglayer, sitting in the corner on the poop board. Upon examining her I found a mess of what I think was dark dried blood and the little pocket of skin at the bottom was filled with MAGGOTS! I took her inside the house and washed the area well and got all the maggots out. She seems to want to eat so I thought I would give her a chance. The tissue in the center and around the edges of this opening are very leathery. Any one ever see anything like this? I have her in a cage with food and water and I will watch her. Any ideas anyone??
