I have a 3 and 1/2 year old orpington hen. She's been "off" for about 4 days. The first day she was just a little late getting off the roost bar. The second day she was also slow to get down and slightly less peppy, with a droopy comb, and tail down. This was enough for me to investigate. However, she's the least friendly of the bunch and she's harder to catch than a greased pig, but I did notice runny poop on her butt and spreading her legs more that normal. It wasn't until yesterday that I was able to get my hands on her. Yesterday she was feeling bad enough that I was able to catch her. Once I got my hands on her, it was immediately obvious that her abdomen was swollen. From breast bone to vent. My first thought was that she was egg bound. I tried to look for spasming of her vent but couldn't see between the feathers, poop, and her attitude. Gave her a bath with Epsom salt. And fed her some Tums. Then once able to inspect, I saw her vent was spasming so I put some water based lube on her vent and allowed the natural movement to hopefully get at least some of in inside. The results within minutes of turning her lose was that she perked up. Her comb stayed flopped over but her tail came back up and she seemed to be much more energetic and lively. Today she was back to being lethargic, and uninterested. I had a slightly harder time catching her, but I think that's just due to the fact that she's wise to me now. Repeated the actions of yesterday, minus the lube. With the same results. However with no egg, or improvement to the swelling. It feels like a firm water balloon. At this point (at least day 4) I figure is she was egg bound she'd have either passed the egg or been on deaths door. So, now I'm wondering what the issue is. The only thing I can come up with is water belly. As far as her diet she's on layer pellets and a handful of scratch. Watermelon also yesterday and today. She's not as interested in food as she normally would be, but still eating some. Any ideas, or possible treatment options please share. A vet is not an option, so it's all self treatment.
