I have a young hen that has not been quite herself lately. Still eating and active to a point, outside in the run daily, but today sitting around with her eyes closed frequently. I was watching her for a while and noticed that she seemed to be straining, as if to get rid of an egg or something. After she was on the roost tonight, I checked her over thoroughly. Crop was not full, soft stomach, and couldn't feel anything in the vent. I was thinking possibly she was egg bound, as she hasn't been laying the last few days. But I couldn't feel anything internally with gloved lubricated finger inside the vent. But, she has a large very hard mass below the vent. It wasn't boggy, as if it was fluid filled, just plain hard. Any idea what that might be? I soaked her bottom in warm salt water for about 30 min. and gave her an antibiotic injection, from something I had from a visit to the vet for another chicken a while ago. I applied proctesedyl ointment (a corticosteroid/antibiotic ointment) to the area. She was happy to get back up on the roost afterwards. I'm very much hoping to see improvement tomorrow, but wow, that's such a hard mass, I really wonder what that is and whether it can be reduced. I'm out of ideas, other than thinking it's an abscess. She reacted when I pressed hard, but I had to press fairly hard to get the reaction.
