I have always mulched-cut my grass as I'm an organic gardener. Unfortunately, I cannot allow my chickens to truly free-range (they're in a large run) due to neighborhood dogs. However, I just got a new lawn mower that came with a grass catcher and thought, geez, I bet my chickens would love the catched grass. So, I made a couple of passes over beautiful St. Augustine grass and poured it out into their run. You would have thought it was Chicken Christmas! They went crazy for it. Can't believe I didn't think of this sooner - just didn't have a grass catcher til now. Now I won't look at the 2 acres to mow as grudgingly as I did before!
