We have a sick little bantam. According to the guy we got her from she should be about ten months old now. Three nights ago she started wobbling and wouldn't go on the perch with her buddies, so I brought her inside to investigate. I tried a warm bath and checked for a stuck egg but couldn't feel anything (also, I don't think she's laid a single egg since we got her five months ago). Her poops are runny but I don't see any undigested chunks of anything in them, or any worms. When I was bathing her and checking for a stuck egg I noticed she was very bony. She generally panics when anyone tries to touch or hold her, and she's super fluffy, so I hadn't noticed her losing weight until the bath. Her bantam buddies are healthy, not bony, jumping around and doing their usual thing. The first day we had her in we gave her lots of nutrient rich foods - superworms, cooked vegetables, etc. - and some high calorie stuff like cooked white rice. She ate almost everything we put in front of her. My farrier said he thought she was dehydrated and told me to make gelatin with corn in it, which I did. She ate it, but didn't improve. She has been drinking plenty of water since I brought her in, so I don't think it's dehydration. Her crop was full yesterday morning so I started to suspect sour crop, but she doesn't smell sour. It wasn't tight enough to be an impacted crop, I don't think. Her appetite had decreased yesterday morning so I made a vet appointment with the exotic vet that I took our rabbit to when he was sick recently. The vet said my little chicken was hot, indicating some kind of disease. He also said she looked like she might have arthritis and maybe she was falling over because she was trying to keep weight off her right leg, as nothing was visibly wrong with the leg but she was consistently falling to the left and was holding the leg a little weird. He gave me antibiotics and a pain medicine for her and told me to give her probiotics as well, which I already had at home. Do young chickens often get arthritis? I was fairly surprised at his guess, as it came on so suddenly (the wobbly walking - I expect the weight loss has been going on for a bit, just unnoticed). Since I paid over $100, I'd like some reassurance that this vet knows what he's talking about. Any of you had any similar experiences? A chicken with arthritis, or just a chicken exhibiting similar symptoms? I really want to like/trust this vet as I've had some bad experiences with vets and really want to find a good one. But if he doesn't know what he's talking about with chickens and he's just acting like he does and charging me a bunch of money... well, I might need to keep looking. Oh, I think he said her temp was 106 something. And this morning she is eating the cooked rice and drinking but isn't interested in the other foods I offered her. Her usual diet consists of layer crumbles, scratch grains, and alfalfa leaves. Sometimes I put out some oyster shell in case the layer crumble doesn't supply enough calcium, though I doubt she's needing calcium if she really isn't laying like I suspect.
