ok. Recently, 2 of my chickens have disappeared w/out a trace. (hawk?) So now im planning on ordering a few more small order chicks. Someone mentioned Guineas are good for predator control. Is that true? Would they alert if a hawk was around? And are they really that noisy? If I can take Margret, one of my Red hens, screaming in the morning, I can take anything. If I raise 1 guinea with 5 or 4 chicks will the guinea think it's a chicken so there for be friendly with them? Is there a certain type that is quieter/friendlier? The selection is on Nature's Hatchery. How is the laying? How big do they get? Thanks, answers greatly appreciated.
