Hi! Just joined, and getting ready for my first backyard chickens. I'll be placing my first chick order soon and have been doing a ton of research on what breeds to get. I know I want a mixed flock, and can only start with 6. I've narrowed it down to these 5 breeds: buff Orpington, Rhode Island Red, barred rock, Sussex, and ameraucana. Should I get one of each and double up on one breed, or 2 each of 3 breeds? I need them to be docile since I have 4 boys under the age of 6, and they will be my helpers....and we eat a lot of eggs so I want producers. What are your opinions? Thanks in advance!
