Three year old mix hen, suddenly not able to walk due to one bad leg yesterday. It's completely without muscle tone-- foot just hangs there- leg flops from the first joint. (The 'Backwards knee'). Side to side hangs, if that makes sense-- it's not hanging down to the floor if I pick her up (although the foot does). Joint feels different than other one - thicker, hot, moves more when manipulated (like joint or bones moving?). No visible breaks or injuries on the part of the leg I can see (scaly part) I'm guessing she twisted/broke/pulled something in the coop somehow. I have her in a comfy crate, she's eating and drinking and laid what must have been one very painful egg. Would love to avoid the vet if possible, but will take her if I must. Starting here for thoughts though. Thanks!
