Hi, I'm thinking of having a few (2) layers in our backyard. I live in Michigan, just inside city limits, but have about 1/3 acre fenced in backyard. I plan on building a coop with a smaller run, but wanted to free range the chickens during most days. My reasons for doing this were for fun, for my kids, for pest control and for fertilizer. I have a lot of perennials in borders that I mulch. I was hoping the chickens would eat bugs off them, but I heard they might just eat the whole flower/plant. I'm not ok with that! I've worked hard on these flowers! I'm also wondering if 2 chickens will destroy my yard. We have quite a bit of grass, and I'd like to keep it that way. Someone suggested I only let the chickens out when I'm there and supervise them, but is this realistic? I'd so appreciate feedback on this, thanks!
