Ok, I'm back. My sultan hen seems stable, but not really improving. I have completed the course of treatment for both bumblefoot (hers was mild/mostly healed already) and mites (again, pretty mild--but I hit her with a combination of ivermectin and the gas and A&D remedy--also treated the legs of the whole flock and cleaned and dusted the coop).
My sultan hen, Snowdrop, is still in quarantine. She eats and drinks enthusiastically when I put food/water right under her beak, but is otherwise not motivated to seek it out. Two days ago I noticed she had bright green poop for the first time. I read that is bile in the poop, which could be a sign of many things, including both malnutrition and infection and even coccidiosis. I started her on a Hail Mary cocktail of probiotics, antibiotics, corid, and electolytes, and gave her undiluted nutridrench by syringe. At first I gave her he cocktail by syringe, too, but then i found she would drink plenty if I sprinkled some mealworms in the water bowl. The green poop has stopped, but her original symptoms continue. She is on day 3 of the cocktail.
She lays mostly in one spot, and walks only backwards 99% of the time. She will take 5-15 steps backwards until she bumps into something and/or comes to rest. I have read this could be an early sign of wry neck or crook neck, which in turn can be a result of injury due to vaulted skulls--prevalent in silkies. Are sultans also prone to wry neck? Does that sound like what she could have? I can start her on the blue egg brown egg regimen for that if it seems like the right diagnosis.
*I will cross post this in the injury forum, but thought you Sultan aficionados might have good insight. Thank you!!
