I lost several chicks last year to bloody poop. Have no idea how to spell the actual condition (coccidiosis?) but I treated it with corid. My question now is if anyone has ever used it for prevention befor their chicks got sick since it is so deadly once they get it? I have 4 chicks now and water them with a chick waterer that looks to be about the size of a quart jar. I am trying to find out how much corid should be added to that size container.
