A few weeks ago I suspected cocci and gave them corid for 3 days. The fecal float test I had done this last week was negative, so I thought I had done it unnecessarily. However after treating for worms and STILL finding this stuff in their poop, I searched and found advice from Kathy (cartsapony) saying to treat for severe cocci. So that's what I'm doing now. Nobody looks sick but my intuition has been waving red flags lately and I think this is why.
I certainly hope after 10-12 days of corid, a second treatment of valbazen, and the ongoing bumblefoot care that everyone will be healthy and happy for a good long while.
