I have 3 plymouth rock chickens in a coop that I clean at least once a week, I clean their water bowls every day sometimes twice a day, and occasionally i let them out to play. A day ago i notices one of them acting lethargic with her wings hanging down, it was not because of heat this was late around 630pm and the other 2 where not doing that. Today she was acting the same not eating and walking funny as if she ware becoming paralyzed with one foot curled up almost like a fist, so i quarantined her, she is very light i didn't noticed until i picked her up, her feathers make her look big and healthy also her comb is nice and red. I noticed in her poop that she has worms, her poop is green and white and its somewhat solid, im treating all of them for worms with wazyne 17. what else should i do? Im planing on giving her yogurt starting tomorrow. Im concerned that I have something that might spread. My first chicken i lost because of a respiratory disease she was gasping for air stretching her neck and paralysis. please help!
