I noticed her bum nasty and got her in the house. I thought last night was vent gleet. So cleaned her again this morning and it is not a swollen vent, but is a thing sticking out of her, is round and attached, red and hard. Might it be a tumor?? There are no chicken vets here so basically on your own. She has went #2, but there is a lot of white on her feathers. I wish I had gotten better pics but trying to hold one angry hen and do it. It covers her vent except right at the top.
