Most of my chickens are free range but not my Silkies.  There are way too many chicken hawks in our area and we have seen them sitting in nearby trees just waiting to get our babies.  lol

We have a septic tank and drain fills.  The grass grows so beautifully over the drain fills and much thicker than the rest of the yard.  When my husband mows that area, I always take the clippings to the Silkies so they get fresh green grass (and bugs more than likely) to eat.

We have a compost bin so the rest of the grass clipping go in there along with the chicken manure that I rake out weekly.
