We just purchased our 7 acres which is mostly open with a good stand of very mature pines, i plan on having some chickens for eggs. I have considerd a few Guineas for pest control, ive never had any. Are they really that good at eating ticks and bugs? I mean is there a noticable difference? I have never really thought they were terribly attractive birds. Do they fly, i mean like a chicken. Would they stay in a fence, the whole acerage.. Ive heard they also eat ants, is that true?
