Here's a 25 sec video, I'm not sure if anyone can tell from this. She's about 9 months old and shows no other symptoms of Marek's, except she's not walking normal, but using her wings to go. Her poop is normal also. I'm thinking it could be a vitamin deficiency also, as she was being picked on. I would hold the fermented feed up to her, so she could eat(they were roosting already) when I got home, because her crop was empty and the others were full, but there was feed still available. She is separated from them now, eats fine, but has been like this for a week now, maybe showing slight improvement. I have given her Nutri Drench in her water and some on her fermented. I gave her 1 mil today directly in her mouth. I figure I'd give her another week to show better improvement. Is that long enough? Thanks.
