Started my new girl on Corid 20%. From what I read its anywhere from 1/2 teaspoon to 1 teaspoon per gallon. I went 1/4 teaspoon to a quart for the isolation waterer. about 1 hour after her 1st drik and already looking like the chicken I bought. But I think its a combination of a few things. 1st and foremost, I bought a good chicken from a reputable person. I could tell by the the time it took to drive home (Moore) that she was having issues leaving her roo and buddies. She was sad. You hear about it, but I think taking her out of isolation for a trip to the run with Gerty really helped. Gerty is the Queen of the yard, and took her in with no fighting and let her tag along the usual rounds. So since they both will be on the Corid treated water, I deided no Isolation and BAM, she started to come around a little while ago.
So to sum it up. I got my favorite chicken from the show, she was stressed and sad, my peeps steered me to Corid, she found a new buddy and started to feel better, and I can rest easy tonight and dream about what diaper print goes good with RIR!
