I have an upright brooder and when I come around the backside to open the door, one of my chicks (copper maran) comes towards the door while the other two (appenzeller and le fleche) run to the other side to get away from me. Is the Copper Maran just more friendly or is it displaying roo behaviour of guarding his girls against me/predator? The le fleche is 6 weeks and a confirmed pullet (she's a banty so the same size as the babies). The appenzeller and maran are about 3 weeks and I don't know how to sex them.
