Hey guys! I have 4 chicks between 3-4 weeks, closer to 4 weeks to be honest. I was contemplating making a purchase and introducing 2-4 new Ameraucana chicks to the flock. Would they be in danger of getting bullied by the older guys? I have a black sex linK, RIR, and two mixed bantams right now? If I do get the Ameraucana, should I separate them until they get larger? Thanks!
