I have a Barred Rock girl that's 8 months old. I have a total of 3 barred rock girls but only one is acting different. Her name is peep and she has liquid poop, its like pure water. For some reason its only her, shes eating less and doesn't act like her normal crazy energetic self. I don't think its Cocci, none of the others are acting any different and she's not acting like she's in really bad shape just more like she has a tummy ache. I think it may be some kind of worm, I've read garlic and apple cider vinegar in their water would help, Is that true? Another question is if one has worms wouldn't the others? This is my first time dealing with something like this so I'm worried, and because its only one I'm not sure whats wrong. PLEASE HELP!!!
