Suggestions for new breeds to add to flock

[Italianmango]

Hello, we are looking to add new breeds to our flock. Right now we have 1 Australorp, 2 speckled Sussex, 2 buckeyes, and 1 barnevelder. They need to be cold hardy, their purpose will be egg laying, and right now the pecking order is pretty good. I feel like no one is overly aggressive so I’d love breed suggestions that tend to be at the bottom of the pecking order. Any suggestions? Also, I know this isn’t really a breed question but which places are good to order chicks that tend to be pretty good/accurate in giving me females when I order females?

Have you thought of Ameraucanas? They are very cold-hardy and are listed as a docile, friendly breed.

I'm sure there are others, but I being a silkie breeder in Wisconsin always thought about getting some of those as they are so pretty too.
