I have not purchased my first chicken yet, but I have tried to read anything and everything about them over the last couple of weeks. According to articles in Mother Earth News, chickens are supposed to eat bugs, including flies. So if you have a fly problem with chickens, what would it be without them? Or is MEN posters just leading me down a path? Although not a main reason for me wanting to get a flock of chickens, pest control is one of the advantages that I am looking at.
