My flock free ranges and I have lots of strawberry and raspberry bushes that grow wild. I was cleaning the coop today and noticed some dropping that had a red tinge to them....Im really hoping this isnt an indication of coccidosis! We do only nipple watering systems but it does rain a lot here and I have seen them drink from other water "puddles". I always add ACV to their water and they have never been sick before. The flock is around 10 weeks old...so could this be from fruit?? or something more sinister? I only saw it on one dropping.
