I noticed yesterday a couple of my hens are not gaining weight and growing as well as the others. I brought them in the house, started them on corid, gave them a dose of safeguard and did a fecal-one of the hens had coccidia very badly and passed in the night. The other hen(12(?) week old jersey gaint) has a few coccidia but I also seen this in the fecal- it was actually moving around it looked very much alive...what is it and how can I kill it? Thanks so much for all the help!
