Hi all, I really need some advice. I have a lame chicken who started with a limp about a year ago and now can hardly walk on her own. She's seen a veterinarian and a cause of the lameness wasn't able to be determined. None of the typical or treatable things we expected. She doesn't seem to be in pain and the vet suggested to just let it ride and see what happens as long as the other hens were not bothering her. They aren't. It's to point where she can't get up on a roost and sleeps on the floor of the coop. We physically remove her from the coop during free range hours and she sun bathes and eats scratch but sits on the same spot the whole time while the others forage.She still eats and drinks but she can't dust bathe and we have to clean her bottom and trim her beak for her. At what point do I euthanize? Her quality of life is diminished for sure but not non existent. I'm so heart broken and I don't know what to do. What are your thoughts? Thank you.
