I need to add to my flock because my rooster doesn't have enough girls at the moment. I keep my chickens as pets, so I want breeds that are going to live longer than 4-5 years. Therefore, I don't want breeds that get very big/heavy, or that lay a ton of eggs. They have to be standard breeds. No bantams (my rooster is too big for bantams). They also need to be able to withstand cold winters, and fairly hot summers. Does anyone have any ideas?
