hi all- me and my mom like to have hens and sell eggs to our friends. now our problem is, many customers and not nearly enough eggs to go around. we live in michigan where it gets hot in the summer and incredibly cold in the winter. so we were wondering what some possible breeds are that lay great but are tame and hardy. personally i do not want leghorns they are flighty and difficult, we love the buffs we have now but they are getting old and this last winter was pretty hard on them. any ideas?
