Hen is about 4+ (5?) years old, weight about 5 lbs. "keel" is fairly prominent. I've rarely been able to hold her so not sure how long its been like this. Low in pecking order, feathers very nibbled by someone in our small flock. Noticed yesterday that her stance was odd, and at night she was in the lower nest box when everyone else was up on their roost. Her legs are in "crouched" position most of the time, she gets around but slowly. Post-bath (which I realize should have skipped now), she is quite alert, appetite is good. I've fed her yogurt, peanuts (with gusto!) raisins & sunflower seeds. Egg is next. Have read several posts on swollen abdomen. Hers feels pretty firm and round, I think a bit more than usual compared to the other hens. But it almost seems more to be her legs having the issue? She moves only a little and stumbles a bit. Am going to call the vet tomorrow but looking to see if anyone else has had this. Poops have been varied and fairly normal. Since I brought her inside today: Solid greenish with bits of white, soft green paste, liquid with green & white, and another more solid dropping, bit of liquid again, and then more small solids. Tried probing with lube & glove, but wasn't able to get in very far. She squeaked. There is a firm spot on the lower left of her abdomen that I can feel near her leg. Just now was straining a bit, only a little dribble of poo coming out, and she squeaked each time. Hadn't done that with earlier poops. Gave her more peanuts and she moved around for those. Now she's resting, laying on carpet. Any feedback appreciated. Thanks!
