First time chicken owner.i got chicks from 8 weeks to 12 weeks. Been in coop and run for a week and a half. My question is when they go to roost it's so much chaos. Is it always like that or is it cause they still trying to figure out their pecking order. I can't even stand to watch it. It's crazy. Up and down roost, pecking, knocking others off. It sounds like thunder in there. I'm afraid of one getting hurt. Is there anything I can do to make it more peaceful or is that just what happens? Thanks
