I have (7) 12 weeks old chicks. I am a new chicken owner so am not sure what is "normal". I am unsure of the culprit, but it appears that one of my chickens has diarreah(sp?). It is a very loose watery stool which has been ongoing for a little over a week. Is this cause concern? How should I treat? They have been free ranging alot the last couple of weeks...I don't know if this has anything to do with it or not. Thanks!
