Unfortunately it doesn't work for me. I am researching on the net. Found this.
if the foot is black then the blood has stopped flowing in it which is a bad sign, but luckily for us his foot is it's normal colour, nice and warm but he cannot feel pain and that is apparently because a nerve might of been severed.
So the person we got Paulie off gave us the number for a good vet that he thought would be able to deal with the situation. So we phoned them up and he confirmed what the man thought about the leg being broken, he said it is best to wait a few more day's then if there is no improvement we could bring him in and the foot will be x-rayed. He said that the healing of a broken foot in a budgie can be quite complicated, and he may have to have it amputated depending on the results of the x-ray.
I feel horrible as I've waited this whole time without getting Marigold to the vet. Well, I have, but they didn't do anything. Marigold is feeling pain. I am suringe watering her as she seems to have trouble getting to the water dish. I might try to make a foot brace for her with a tooth pick and sticky tape.
