That is what I was thinking Dood, but how when I have kept all cages clean and power washed, I culled the other doe, this doe and that never were near each other. I clean daily, I have been extra careful. I just don't understand. My last litters were all fine, I prob had 15 kits from different litters and none of them had ec, just that one in my.previous post. Makes you want to throw in the towel although I know that when a person has 30 holes, it is going to happen at times. Any advice?
