People who don't or rarely worm:
I'm switching to katahdins from a breed that I wormed as a flock several times a year. The sheep I'm getting come from a flock that does fecal testing and culls sheep that need worming, and that's how I intend to manage now. I got rid of my old flock several years ago and the pasture has rested since
But. In the past I always routinely wormed new sheep to the farm with Cydectin because they are stressed and also not to introduce someone else's parasites. It was part of my quarantine routine.
People who fecal test and deworm only the sheep that need it, do you still routinely deworm all new sheep? What's your new sheep introduction protocol?
