We lost 2 rounds of litters from 4 does to the heat except 5 I butchered of the older group and 3 kits that were alive yesterday. Over 20 rabbits. We never had a problem last year and certain rabbit groups are just fine so I think the problem lies in a cocci infection. I've been getting a lot of bad livers lately. The ones infected are too weak to handle the heat. Putting corid in their water isn't working though. It reacts with our well water making a disgusting film and then they don't want to drink. I think I'm going to have to hand dose each rabbit once we are sure no one else is pregnant but we only go to the stable every other day. Would a month of corid (amprolium) every other day take care of it or would it be a waste of time?
