I have ivermectin past 1.87% and need to dose one sick chicken. I'm also treating for cocci. She's been sick over a month and hasn't been treated for anything. I was told to just try to get her weight up. She's isolated in a large dog kennel in her own bedroom. Less than one year. Buff orp. Sweet little chicken. Only eats lettuce tomato and bell peppers. I'm force feeding a gruel. Almost put her down today because for the first time ever she looked pathetic last night but when I came to load her up for the deed she was eating her yogurt so we are gonna give her one last aggressive chance. I'm gonna force feed aggressively for a couple days then medicate. I was scared to worm her before because she was so weak but this is it. Wish us luck! What's the dosage for one sick chicken? Her poop is dark brown right now. Almost normal looking... not sure what else to add. Very underweight large bird.
