Hi Rebekah,
I just sent you an email and then found this post from BYC sitting in my Inbox next! LOL Glad to see ya made it to BYC.
I would suggest getting or building a small coop. There are lots of idea here on BYC to choose from. You might also be able to find an old shed or something on Freecycle.
As for the cold, all you need is something warm enough to keep the water from freezing. I have a 10x12' Royal Vinyl Shed and housed about 20-30 birds last year in it. The ventilation is so important because during the winter months the birds will spend a lot more time in the coop. More time in the coop adds up to more droppings on the floor (and elsewhere!). More droppings add up to increased amounts of ammonia which leads to respiratory problems if the ammonia amount gets too bad. Basically, if you can smell it and it seems strong to you, it's too strong for your birds.
Other than that, because of the colder temps that you typicaly get over on the eastern side, I would suggest looking at breeds that have smaller combs. Having said that, there are so many factors to consider. Here are just a few:
1) Eye Candy. Which breeds/varieties do I like and not like? This is purely personal preference.
2) Egg Production. How many per week? What size?
3) Egg Color. White, Brown, variations of Brown like tan, Blue, or otherwise
4) Meat production. Will I raise birds for my own meat?
5) Feed Cost Ratio. How much do I need to feed a particular bird to get a dozen eggs or raise it to butchering size?
6) Geographical/Weather conditions. Does a particular breed/variety do well in my environment?
7) Personal Use or otherwise. Do I want a simple backyard flock or will I be breeding, showing, or selling my birds?
Those are just a few things that might be helpful for you to think about.
God Bless,
