Welcome! My favorite bird (pictured in my avatar) lost one of her feet to frostbite last winter! She moves around just like the other chickens and I've seen her scratching with her nub (lol). The one thing I hadn't expected is that I needed to make her a safe nesting spot close to the ground—she can't get up to roost with the other birds. But she sometimes snuggles with the ducks ◡̈
