I let them walk Stam prefer a natural balance. I would suggest picking up a copy of A sand county almanac but being over 50 you are probably what they call set in your ways. I call it something else but you get my drift. I do have a sow bear with the shiats painting a corner pasture this week . It's not the normal plum shiats but she is on the fruit right now . She is packing 2 of this years cubs so I am worried about her.
