That'll definitely be a good start. I might just add some whirly birds... but I'm very limited in this experience and very much defer to others. My favorite and preferred is Woods' style or essentially three sided building with as much ventilation as possible on the one side... either the whole thing or up high and down low. One thing I do know is that it isn't just ambient humidity that matters as some might not realize the birds exhale a huge amount of humidity when they breath... to that the general recommendation for ventilation is 1 sq foot per bird. I have never achieved this, and live in a high humidity area... but don't generally face any freezing. Pretty sure Folly's place faces it yearly.
Hey, your ahead of the game already... since you found BYC! Those birds will grow sooo fast!
So many wonderful breeds... so many personal choices and goals or needs, uses and environments... paper facts never really add up to real life. But for fun, I do have several comparison charts bookmarked... I LOVE Rocks, Marans and EE as flock mates and pets.
