We have 7 chicks under a week old and I've noticed some pinkish blood in stool. I think it maybe one chick in particular, I've separated her, in case it is her. She's a bit on the lethargic side. Their bedding has remained dry and clean, I do paper towels on pine shavings and change them twice a day. We have been feeding purina medicated start and grow. The TSC suggested the chick electrolytes but did not recommend treating for coccidiosis because they said that would be a lot of antibiotics (with the feed and corid). Any thoughts? Is it likely coccidiosis? We've raised chicks before but I've never had any issues like this. Any help would be appreciated.
