I have one year old hens who I suspect have coccidios. Not my first batch of chickens and have treated before. Lethargic, loss of appetite and bloody stools. Started Corid. Lost one hen yesterday and nursing two other today. The problem, which I'm new to: sick hens all have fluid filled crops that will not empty. They bend over and must vomit into mouth because they drink it. Actually saw one expel liquid. It smelled like vinegar. What an I suppose to do? Medicine is in water and can't withhold it. Please help! I don't know what to do
