My 9 month old hen has an area below her vent that is terribly hard, blackish, about the size of a golf ball. It's as if the tissue is dead or dying or some sort of mass. There is red viable tissue all the way around it. She is not yet laying and my vet says she is not egg bound but has never seen this before. Vet says could be spider bite (since brown recluse spiders are very common at my house), an abcess or a tumor. I try to keep her as clean as possible (for a chicken) by spraying her with warm water twice a day and treating her with Tricide Neo w/Clotrimasole and now blue lotion. Vets says we can't give her an oral antibiotic if we ever plan to eat her eggs. When she tries to poop she makes a whizzing sound and her poop is really watery. When she goes it just runs down the area an makes a mess. Other then her bottom, she is healthy as everything. Eatting great. I've tried putting her out with the other flock since she is happiest there, but they are pecking her sore area so for now she's in the house so I can keep an eye on her. Does anyone have any ideas? She is my absolute favorite. I don't want her to be suffering but don't know what to do. Thank you!
