my African grey recently developed a lump on his face between his eye and his beak and he keep scratching it with his legs or the side of the cage. he allows me to touch when i'm patting him and doesn't seem hurt when i do. i'm afraid it might be a tumor since it feels a little hard under the skin but i'm no vet!! i will schedule a vet appointment but wanted to check if someone has dealt with something like it before. please check the pictures attached.
