I think I already know the answer to this question, but I thought I'd get some opinions from those more experienced than I. This morning I brought a group fecal in and did a fecal float on it. It was more or less negative, except for a few coccidia. I was not surprised, but that leads me to wonder where to go next. In any other animal I've dealt with (dogs, cats, lizards, etc) we would treat even if we saw only one coccidia oocyst on a fecal. But is it really worth treating my chickens when no one is showing any symptoms (the stools are normal, I just wanted to spot check a fecal as I plan to do this every few months and only worm if necessary) and they free range in my back yard which is already infected as there is absolutely no way for me to pick up all of the chicken poop? I do pick up poop every day or every few days, including the chicken poop, so I'm not too worried about them getting a heavy infestation unless their immune system goes down for some reason. Right now I'm leaning towards not treating, but like I said I'd like to get some other opinions.
