I have a turkey gobbler that has had a swollen face for about 3 weeks. He walks around looking up. The swelling is between his eyes and beak. I caught him to check it out and noticed he has clear drainage coming from his eyes and inside his mouth when I squeezed on it a little. He sneezed twice after I did this and acted like he felt better. Do you think this is a sinus problem? How do you treat this?
