I have a silkie hen that I've had for approximately 8 months who started hiding in a nest box with half of her face swollen three weeks ago. I brought her inside thinking it was just a respiratory issue since she had a lot of nasal discharge but she didn't respond to Tylan. Then I noticed a scab inside of her mouth so thinking Canker I treated her for over a week with Metronidazole. That didn't help at all and the inside of her mouth continued to get worse. Now I'm thinking she must have wet fowl pox. She has been isolated for three weeks and no one else has shown any similar symptoms. She's been getting Penicillin injections, since she can't eat she gets tube fed three times a day with Kaytee bird formula, Nutri-drench, ACV, and raw duck egg yolk. She will drink a little bit of water on her own that has oxine in it. I swab her mouth with iodine tincture. I've also tried listerine, clorox, and human canker sore treatment to try and soothe it but nothing seems to help. I clean her mouth three times daily with peroxide too. Chunks of white stuff builds up in her mouth and pulling it out seems to reduce some of the swelling in her face but it also makes her bleed some. Now her ear is leaking a clear liquid and the sores have pretty much corroded the one side of the slit on the roof of her mouth. There is a very small sore on the other side of her throat but her tongue and airway are completed unaffected. Does anyone have any suggestions? I have NEVER culled and really don't want to start now, and for her to last thing long she really must have a will to live. Help!
