I have 6 chicks. I just want them to be pet chickens. I've been handling them all each day but by now I clearly have favorites. Is it okay to just not handle the chicks that don't enjoy being held as much? Or will they turn into wild and crazy chickens when they are adults? In other words is handling necessary if all you want is chickens to go in the coop at night, don't freak out when they see you, etc.
