So it's spring time and, as I though, sickness is starting to get into my flock. One of the pullets I have, probably 8months or so, had poop on its butt that was caked. I did what I could to clean it off but I have also noticed that she has been less active today, standing around much of the time closing her eyes. I went to the run today later on to check on them and only saw 6/7. I went into the chicken coop and found her roosting. This is very unlike her or any of them because they normally stay outside until it is just about dark. She still have 3 or 4 hours of daylight left. That is when I took her down and started trying to clean her butt. When I was doing this she then started puking water, not sure if this is because I was holding her angled down so I could get her butt or what though. Anyway, with the intro out of the way, I have started them on CORID but I have no clue what the dosage should be. The directions say, "Add CORID to drinking water at the rate of 16fl oz per 100gal. At the usual rate of water consumption this will provide an intake of appx 10mg AMPROLIUM / KG(2.2lbs) body weight. I have a 2 gal water container. I put 1ml worth of CORID into the 2 gal of water for 7 leghorn chickens. Am I right?
