Do you have children? If so, you MUST have at least one EE for the green or blue egg. I vote for a mixed flock. Why have a bunch of look a likes, when you can have a whole bouquet of colored chickens? What is your climate? If you put your state in your profile, it will help folks to respond with information pertinent to your region. If you're in a cold climate, I recommend that you avoid birds with feathered feet and large combs. Check out Henderson's chicken breeds chart for a good list of your options. Do you want a hen who goes broody? Do you want lots of eggs? Want a varied color egg basket? Will you allow free range? Keep them confined to a run? All of these answers will affect your breed choice. The most important thing is that you provide adequate space for them. A minimum of 4 s.f./bird in the coop, at least 10 linear inches of nice wide perch/bird in the coop (2 x 4 laid on the flat side works well). 1 nest box/4 birds. A minimum of 10 s.f./bird in the run. Lots of ventilation, spaced well above roosting level. All openings in the coop covered with 1/2" hardware cloth. The biggest mistake new flocksters make is starting with a coop that is too small, expecially the pre-fab ones that are oh so cute, and oh so very small, resulting to lots of problems with behavior and chicken health. Build your coop and run bigger than the needs of your intended flock size.
