Hello all! I currently have 3 Buff Orpington chickens, 5 weeks old. I want 2 more chickens and feel I need to get them now so that I am not mixing them when they are much older. My husband wants RIR. I have read some reviews that says they can be agressive towards other chicks. Is this a bad idea to mix the 2 breeds? Are Buffs just too nice? Thank you!
