I've got a few year-old hens (and possibly the roo) who are passing bloody poops, are a little bit off their feed, and have had pale combs and wattles for a week or so. The bloody poop started two days ago, so I started everyone on Corid yesterday. It's been extremely hot and humid here and the flock is in an uproar establishing the new pecking order as the chicks grow up. No changes with chow, water, or recess (they get to free range while I'm out with them a few times a day. My set up is all sand and I keep it very clean and dry, but we did have a nest of wrens inside the coop last month. (I couldn't reach them to get them out.) My question is, do I need to stop feeding the medicated chick starter? I've got six seven-week old chicklets that were broody raised, so everyone in the flock is eating the medicated baby chow. I'm only putting one teaspoon of Corid per gallon of water, so it's not the full dose for a bad infestation. I have my fecal float test ready to send in, but am pretty sure they've got coccidiosis. Here are some poop pics if anyone is interested.
