Every day I let my chicks out of the brooder into their run for a little while and they go CrAzY! They get along fine in the brooder, snuggling & loving on each other but as soon as they get some space they start running around chasing everbody and jumping thru the air at each other. What are they doing? It's kinda fun to watch but then I get a little uncomfortable like I should stop them! Is is just horseplay or determining the pecking order?
