Several weeks ago I posted about my chicken having a yellow mass in her mouth. I treated it with iodine and vetericyn. For a few weeks now I've had her separated from the flock, I've given her Tylan 50 for her cough....which is much better, and I have been able to remove the mass in her mouth. It came right off with no bleeding. But now after a week, her mouth is still sore, it's bleeding a bit and she still has a hard time getting anything to go down her throat because she can't hold it right with her tongue off to the side and her beak is a little misshaped from this mass that's been on her for a couple of months now. She has a great appetite and eats as much as she can. But she is very skinny!! She has not gotten any worse nor better. I think the problem hindering her from gaining weight is that she just can't eat like she used to! Is there any general antibiotic I can administer or put on her mouth to get this healed up? Thanks for any suggestions!!
