I currently have 19 chicks that I hatched (EE, WYANDOTTE'S, BARRED ROCK) , the ultimate goal is to have 9 in which will be re homed. They are 5 and 6 weeks old. I've recently moved them all to their new coop I built. Raising chicks is new for me. I have a few cockerels at this time that appear to be fighting? They flare their neck feathers, jump and peck each other! Is this normal behavior? It kinda scares me , and makes me want to separate them.. will they hurt each other? What should I, or shouldn't be doing? Please advise.
