Hi everyone. I am brand new to Backyard Chickens and have many questions that perhaps you can help me with. My husband is building a movable chicken trailer for our back yard and I want to get 3 chickens who are friendly( they will be pets) & lay a lot of eggs. I would like to know if its easy to mix the breeds so I have 3 different chickens & if so, what's the best combo? I live in NJ. Thanks!
