It's precious of course! I love how he's adapting so well to the cone and his foot that he doesn't even seem to know that he's different. He is such a special little guy!
I'm just glad he's actually adapted. He was miserable before, but he's having a lot of fun with his hut. He's even tried to climb ontop of it, but it's just a little too tall.
Is it his entire leg that will wither and fall off or below the knee where the band was? I had a friend with a crimson belly conure that had a broken leg, untreated by a breeder, that he adopted. The leg was too far gone at the break and there was nerve damage. And the foot was turned around sort of. Vet took the foot off and the bird developed a stump at that point. With a little home PT to strengthen the leg muscles he learned to fly and land safely. It was amazing to see this little guy who had no foot from ankle down do what he could do.
Below the knee where the band was. It looks like he'll have some of his lower leg, it's already healed over, by the looks of it.
Do you know what kind of exercises your friend used for that poor conure?
It's disgusting what people will do with 'breeder' animals. I just don't get it. Even if you ignore the animal's suffering to look at it from a purely financial standpoint, getting your birds seen by a vet would net you more profit in the long run. Either because people will pay more for the animal when you sell it, or because it would be more inclined to breed and more capable to breed and take care of their young.
