I have had 3 kinds of clover, along with preanial rye grass, orchard grass, some timothy, and of course the native cheat grass, in my 8 acres of pasture. The summer drought came along, and in spite of feeding hay early, the cows turned the pasture into a brown golfcourse. No other place to put the cows, other than in the yard. The fescue, that is in the chicken yard, held up real well, and stayed green, all the way thru the dry spell, which ain't over yet. If I sow fescue over the existing grasses, will the cows eat it? Will the fescue crowd out the other grasses, and clover?, or will I end up with a drought proof green pasture that is no good to me? That is if the rains ever come, and I can salvage some of the existing roots!
