Hi all, I've a little hen who has developed whitish grey "bumps" on both sides of her beak that itch her terribly. I've given her a bath in a citrus product, used a greasy ointment on it, nothing that I've used seems to help. My other girls aren't bothered, but she in torture. Anyone have ideas on what they are and how to get rid of them? I do want to say she is a rescuee that's been very sick in the past. She has lung and heart problems, but she's a sweetie and even raised 2 chicks successfully. The other hens tolerate her, but certainly not close to her so I think they'll be ok.
