My Lineolated Parakeet was walking on his cage and got his foot caught. in a panic he flew away but scraped his foot while doing so. theres no blood but he is only standing on 1 foot and seems to be limping on flat surfaces. i took all of the perches out of his cage and gave him a blanket to sleep on but im still worried. will it heal by itself or do i have to break what little money i have to go to a vet?
