I'm going to hatch some eggs in my kids' classrooms this spring. The chickens will live at my parents' farm. (They're just starting a flock and we thought this would be a fun way to do it.) We're hoping to have chickens that are pretty docile since they're be around kids a lot, pretty decent layers and also cold weather hardy (we're in MI) Like maybe some of these: http://www.mypetchicken.com/chicken...r=0,1&b=0,1&c=2,3,4,5,6,8,9,12&d=1&l=2&page=1 Anyway, we'd like about 40 eggs. Does anyone have any recommendations on where I can buy a "variety pack" with some of these? We'd especially like to have some barred rock, but other than that . ... just a variety?
