hi, im new to this raising chickens thing, but am very excited. i have alot of questions and am worried i might be doing it wrong. any ideas or advice would be greatly appreciated.im just going to start with 4-6 chicks.i live in minnesota, so winters are long. what are some breeds that are hardy enough. i just built a brooding box out of plywood, its almost 4 foot by 4 foot and 2 feet high, i put a removeable partition to cut down size in the begining. is that too big for a small flock? i can reuse it for future birds. the coop is almost done and is 5 feet by 8 feet and 6 feet tall. plan on having 3 nesting boxes and 1 openable window, the roof overhangs will be just chicken wire for cross ventilation. in the future i wanted to plan for maybe 10-12 chickens. im i planning this o.k? also, i want alot of diverisity with the flock. is it a bad idea to get 1 chick of each breed or should i get pairs ? will they fight? thinking 1 silkie, 1easter egger, 1 barred rock, and 1 leghorn. im sure everything will be o.k, but im still very nervous.
