Best of English Farrowing Hut special. Duplicated my first pasture farrowing "hog" panel hut - a little. It serves to keep the cold and wind out, and provide a relatively clean and protected place for the birth and for the young piglets.
The new English arc-type hut (B) shows promise but needs more evaluation.
The English Style Farrowing Huts are working pretty well so far.

The huts were randomly arranged in farrowing pastures. These are just going to be sectioned off from the main pen so. I probably should have spaced the huts farther apart.
