I have CIDRS in a group of cows and heifers that I am going to remove tomorrow. Does it matter what time they are taken out? I know the ones in the heifers are staying in 6 hours longer than the cows, but I didn't know if I had to take them out of the cows around the time of day they were put in, or if it didn't matter. I was told it didn't matter as long as they are bred a certain amount of time later, but I'm not sure.
