well it could be them establishing the pecking order so if that is the case it should settle down in a couple days, if its not then something is not adequate to them, either not enough room, or not enough feeders/waterers, not enough roosting space, one too many broodies maybe?? do you have enough nest boxes? sorry I know loads of questions but its hard to determine what is really going on without much info to go by. Did you get all your chickens at the same time, if not have you or has there been a recent upset in the coop, anything changed etc, an addition??
how are things inside the coop? are they being allowed out to range or in a run to stretch their legs, do you think maybe they are bored? chickens do get cabin fever if kept in too long and they do tend to get bored and a bit cranky.
there are plenty of questions for you to consider, when my girls begin to get on each others nerves I tend to investigate the reason, sometimes there is a bully in the pack and I settle that down rather quickly by grabbing the bully and either separating her for a couple days or carrying her around under my arm so she knows her place. I recently had a bully and they were all at each others throats when I removed the bully things calmed right down after three days I let her back into the coop. and Voila, all was good.
Observe your flock for an hour or even a couple and you might get the idea where the issue lies.
