Hello everyone, I am a beginning chicken (and back to basics) enthusiast. I am looking for any advice and help on choosing a good breed of chickens. I live in a northern climate, so I am looking for some cold hardy chickens. Also, I am looking into generally dual-purpose birds, leaning on the egg production side, but I am very lax about this. Some options that I have been looking into are: Sussex, Delaware, Austrolorp, and (maybe) Plymouth Rock. I am also very open to any tips and advice that anyone could give. Thanks a lot!
