I'm thinking of adding a dexter cow and a pair of guinea hogs to.our farm in the next couple years and was curious about maintenance. Do they need hoof trimming? How frequently? How old do you want the girls to be before you breed them? Could I run the three of them together with 6 goats on 4 acres with just a little supplemental hay? We've got 3 acres of good pasture, some brush, and about an acre is trees with sparse grass. Thanks in advance.
