I'm getting the six baby chicks in February. Which breeds should I get? I have two young kids so they need a sweet disposition and egg laying is the next priority. My coop is 4x6 with 3 nest boxes and a yard to play in so size is not really an issue. These will be my first chickens so easy care will be a nice attribute. I live in Washington with mild winters, but we do get snow. So winter hardy too please. Thanks in advance for your input!
