My husband surprised us with chickens this weekend. Each of our sons got to pick one out and name it. We have had the birds for three full days now, in a temporary coop. Here is my question: We might want to build a chicken tractor that we can scoot around our 2 acre wooded back yard every few days. 1) Will this just spread poop around so that we step in it whenever we go in the yard? 2) Will this help control flies next summer, or make it worse because the poop is over a larger area? I was just very surprised at the flies after three days of fall weather and want to avoid problems from the beginning if possible.
