I am so excited. I am getting hens this spring for the first time in many years. My dear hubby is building my coop. I want to order chicks and was wondering which way to go. I was thinking that I would like to have 2 Plymouth rocks, 2 golden comets and 2 Silkies. Can I do this? Can I mix the breeds? Will one tend to pick on the other? Thanks for any advice you might offer!
