Hey Debbie!
So....I am I to understand that you don't have chickens yet?
If so, do you want eggs, meat or both? There are many great dual purpose breeds out there. There are also many specialty breeds that are fun to have.
How many do you plan to have? If it's a small amount you can start small, but honestly, you'll probably outgrow your original plan (talking from experience here!). You can start with a med-large chain link dog run, or you can go all out and build a super deluxe area.
I would go out and try to get a copy of Gail Damerow's - Storey's Guide to Raising Chickens, there are many, many good bits of info in there.
I have many different breeds, and I do have my favorites.......
fell free to PM me and we can discuss!
ETA, I also have some babies if you want!
