Read your post about Marek's, please look at Rock Star's picture & see what you think. She's been sick since Saturday, not eating well, hanging her head down, runny poop, I've seen her throw up twice, she's also lost a lot of weight, noticed one of her wings drooping yesterday. I began Duramycin in her water Saturday and have treated the lesions with anything from Vetericyn, Neosporin, Derma Vet, Silver SUlfadiazine just hoping to see a positive reaction from one. Today I began Electrolytes & am currently trying Derma Gel on the lesions, along with the Duramycin still in her water. She is much more alert, not hanging her head or drooping the one wing & eating enthusiastically. But if it is Marek's, should I try your treatment recommendation?
