My duck has a bump on his beak and I'm concerned it might be serious. RE-POST WITH PICTURE?

My duck got bit in the nose by a dog (nothing serious) and after two to three weeks it turned into a nasty bump . Anybody know if it's serious?
Update: I will like to let everyone know that I am not in a financial position to go to the vet but I will do some research on the price of a few places nearby
