Well, my 'math' hasn't caught me yet as I need a bigger coop. I have eight hens. Five Black Australorps and three Blue Andalusians. I get 7-8 eggs each day! They are very good girls. I want some chicks this spring is why I'm asking. The roosters (I saw online) in both breeds are very handsome. Which one should I pick?Pretty breeds you keep! I would get only one rooster unless these Australops and Andalusians are kept separate. One roo per flock. How many hens do you have?
