Arthur Thomson:
Dan we had Bermuda grass, then we got about 10 chickens,
now no more Bermuda grass, just lots of fresh eggs.
me:
@Arthur Thomson, I love the idea of chickens for mowing grass;
what else do you feed them?
have a favorite book how to get started?
. had a problems with coyotes?
well, they could be kept in a movable wire box!
Arthur Thomson:
Philip, my wife tried that beyond our garden fence
between the street and our fence
with a portable wire box about 6 feet x 5 x3.
It was gone next morning haha
