Hi my bird canary has a white quite big lump on his toenail and it sometimes bleeds it stands on the other leg i don't know whether or not to take it to the vet or not.
Yes, please Find an Avian Vet to examine and treat your bird. Dr B can not tell what is causing this or prescribe something to help it over the Internet.
This could be bumblefoot, a tumor, a disease or an infection. No matter what, your bird needs treatment to get better.
