As much as I have appreciated Davaroo's sage advice on many topics, I have to say that I love my flock of many colors. If you are focused on utilitarian values, production, scientific analysis of specific characteristics, etc, well, that is one important side of the issue, but the other is the aesthetics! Chickens are beautiful birds, and the variety of feather colors and configurations - to say nothing of personalites - is so entertaining and rewarding. I say, try a few of each of the ones that light your fire, and go on from there. One could go overboard, but the water's fantastic!
