Some other breeds are blue copper maran, blue birchen maran, blue cuckoo maran, blue cochin, blue orpington, and lavender orpington, and dark brahma.
Marans lay very dark brown eggs, and are pretty friendly birds. They lay about 3-5 eggs a week.
Orpingtons are giant, fluffy birds that lay a light brown egg. They are super sweet and make good mothers if you let them hatch eggs. They are good layers with about 4-5 eggs per week.
Cochins and brahmas are HUGE birds that lay a light brown egg. They have feathered legs and are very friendly. They don't lay many eggs (3-4 a week) but they are great pets.
I have all 4 breeds and personally love all of them.
