I am plan on having Brahma, Salmon Favarolle, Orphington, Silkie, Red-Sex link, and true Ameraucana. I am wondering if I should have a roo and which breed would be friendliest. I don't want a mean roo and I can't talk myself into having freezer animals. I read somewhere that fertelized eggs are more nutritional than non-fertelized eggs? So should I just have hens or should I have a roo too?
