I just finished reading a terrific article about using Guineas to control the bugs in the flower garden and yard. So do they not eat the flowers? This is a great idea if it is true since we are a registered wildlife habitat, we cannot use much pesticide around the property. Which are better to have males or females and is any specific variety better than another. I sorta like the pearl and lavender varieties. Oh, and how do you keep them from flying off if they are just allowed to "free range" in the yard? Or do they not fly? I have also heard that the hens can be very vocal!
