One of our hens got frozen feet. Happened last year, too. Only this hen and she lost her claws. Must have a circulation problem because it was only this bird. The others are ok. Lots of nice fluffy bedding and wide roosts. Anyhow, this year they froze part way up the leg even with all that bedding, etc. I feel just awful. We have thawed her out and keep her in the house, but she has lost one leg and can no longer function. She is miserable. What is the kindest, quickest way to end her life? Considered giving her the cat's amitriptyline but was afraid that would just cause seizures and make her feel worse. Thanks in advance. I feel like a very bad chicken keeper.
