I'd like four laying hens as pets and for eggs in my suburban yard. They will not free range. They must be hardy to dry heat and cold winters. They should be quiet and friendly. I cannot keep roosters here, so breeds that can be sexed young are my preference. Here is my list: Ameraucana, Marans, Cochin, Faverolle, Red Caps, Araucana, and Orpington. Am I on the right track? Would it be appropriate to have four different breeds?
