Welcome. I'm glad to see you doing your homework before running out and picking up a handful of little fluff balls from
TSC! It would be helpful for you to put your general location in your profile. That helps when folks are trying to respond to any questions you may have. My recommendations: Start with a review of Henderson's chicken breeds chart. Then, go to several of the web sites of the hatcheries you're considering ordering from. Look at the breeds you're considering there. Sounds like you'd eventually like to breed your own. Good for you! I'd love to see everybody who can keep a rooster breeding their own replacement chicks. After you decide how many birds you want to keep, it's time to plan your brooder, coop, and run. Plan on at least 1 s.f./bird in the brooder. Plan on at least 4 s.f./bird in the coop. Plan on at least 10 s.f./bird in the run, even if you plan to let your flock predominantly free range. There will be times when you need to pen them up: training them to lay eggs in the coop, keeping them home when they discover that the neighbors yard has greener grass or beautiful flowers for them to destroy, local dogs come visiting... or you have predators find your babies. Now that you have your ideal flock size in mind, and an idea how much space you'll need for brooder, run, and coop... DOUBLE THAT! Because, after you get your flock up and running... after a season or two, your egg production will drop off, and you'll need to start some new chicks. While some folks practice all in, and all out style of management (they kill all of the old birds, then start a new batch of chicks) most folks prefer to start a few chicks every year or so. That takes extra room. And if you have chicks, plan on at least 1/2 of them being cockrels. When their hormones kick in, they get nasty to their sisters. You'll need extra space for a bachelor pad.

My favorite breeds: I live in Maine... = COLD weather in abundance! So, my preference is a bird with a small comb, and non feathered feet. Also a bird that has a good coat of feathers. Then, there's my preference for a colorful egg basket, good laying productivity, occasional broodiness, good foraging, and good temperament. Then... there's the pleasure from having a bit of eye candy moving across my yard. So, I choose birds with pea or rose combs. EE, Dominique, Wyandotte, Rose comb brown Leghorn, with a splash of Pioneer thrown in to produce a sizeable egg and carcass. Because I'm working on producing my own back yard flock which meets all of my criteria, I started out with all of these breeds, and will continue to cross them, and cull every year to see what comes out in the wash.
Now, if you plan on having more than one breed, and eventually having a rooster... you might consider choosing several breeds that, when crossed will give you sex linked chicks. Check out the charts on the first post of this thread:
