Help!! I am brooding my chicks in my coop. They are 5 weeks old, not on medicated feed. Found one dead this morning, the chicks have blood on them and I realized that atleast a couple of them out of the 20 had reddish/bloody poo. They were completely fine at last close inspection about 3 days ago, no blood in coop. Adult chickens and ducks seem fine for now. I am assuming it's coccidiosis. I have never had it before so I am unsure how to treat. But I am about to head to TSC.
Here's a poo from this morning:
