Hi! Very new here and researching chicken breeds like crazy before I turn in my order form, deciding what chickens we'd like to have in our backyard flock. We have .5 acre yard and will be building a stationary coop with ample run, but letting the birds loose when we're out with them (hours and hours and hours in the spring, summer, and fall as we have two small kids, a garden, and lots of outdoor activities). If all goes well, we are planning to retain the same flock as long as we can (i.e. beyond the two years or so that the chickens are expected to be laying the best). I'm really hoping to have a few really tame, friendly birds in the mix for my 4 and 2 year old. I have read over and over that socializing them as chicks is what does this, and we will be trying hard to do that. Anyway, I'm rambling, but I was thinking 3 Ameraucaunas, 2 Light Brahmas, and 1 Black Jersey Giant. I know the BJG is big, but reviews lead me to believe that they have a fabulous temperament, and I kind of don't want to miss out on that... If you had the choice, would you stick to just one or two breeds or sizes, or does this sound like a nice, varied flock?! Am I asking for trouble with the mixed size of these birds? Lastly, i have heard that baby chicks can be very "dusty" when getting their feathers. Too dusty to keep in the house? (I was planning on keeping them in the living room.) Sorry for the obvious newbie questions! Thank you!
