I have a flock of 12 chickens in suburban St. Louis. I have a decent sized area for them (approximately 15' x 25'). A friend who works at the farm ranch for the local Humane Society took in a lone Guinea chick and contacted me about it. I'm familiar with them, I know that they are great for bugs... But most people I know with them have room for them to range and make noise. Can someone please give me the basics on Guineas (the good, the bad, what you need to provide for them to be happy)?
