I have a silkie pullet that's only about 3 months old. I've had her inside for a few weeks now after she recovered from a bad case of cocci. But now she's looking sick again. There is no blood. Instead her poop has been very slimey and sometimes greenish. She has nothing in her crop and she doesn't seem to be eating. Could this be a reoccurrence of cocci or something else?
Why not treat for Cocci again just in case? It seems likely (in my opinion) that the last treatment may have only slowed the Cocci temporarily. I would try a larger dose of Corid, since there are different dosing guidelines based on severity. Search this site for "Corid dosing". Also, instead of dosing in the water, which they might not drink enough of, I'd dose with a syringe directly into the mouth.
