Thanks, I've been reading up and saw the liquid dosage on this page: https://www.backyardchickens.com/a/coccidiosis-how-to-treat-it but did not know the powder dosage.
I've already changed the water and cleaned the waterer today, and will start to medicate tomorrow.
There was another bloody poop this afternoon, so I'm thinking this is coccidiosis. I think I'm going to try to get some corid tomorrow and start them on that.
One of my 3-year-old bantam Brahma hens left this bloody stool in the nesting box today. I'm not sure which one, as I observed the hens, and all appear to be acting normally (except the one broody hen I have). I checked the poop chart, and it looks more like one of the last 3 normal poops, but...
Raleigh does not have any ordinances concerning backyard chicken keeping....
