Buried in grass

Because of last year’s heavy parasite season, this year we kept our sheep off of most of our fields until about July 1. Of course, those fields didn’t stop growing simply because there were no animals to graze them. Keeping up with spring growth isn’t easy even in a normal year, and this year I’m […]

They’re out and free to graze!

I’ve written often this year about the problems that last summer’s hot and wet weather created in producing the “perfect storm” for these icky critters. Although we have been selecting for […]
