I am a backyard chicken owner who just bought an old farmhouse on 26 acres! My question, we will not be moving over there for another year or so, but was curious if I could go ahead and get a few guineas. How self sufficent are they? I have heard that they will roost in trees, etc.. and a coop is not necessary. We won't move or chickens until we are over there on a regular basis. I just need to hear your thoughts. Thanks!!
