We recently bought new chickens to expand our flock. Our existing flock is very serious about the pecking order. I don't know how to introduce the new chickens without them getting seriously injured/killed. The new chickens are three weeks now, so we're not letting them out yet. When we do let them outside we want to know what to do to introduce them.We want them to be able to free range together without someone getting hurt/killed. The new chickens are already starting to determine their pecking order. The two chicks Amber and Midnight are starting to face off, but they don't understand Nugget is dominant outside. We have never introduced two flocks before. Please help if you can. Thanks.
