what's the weather doing? if it's too cold or raining that might explain it. otherwise, try feeding them only in the run for a few days. or put them out and close the door so they can't rush back in. again feed/water them outside, and they'll get the idea.
i can't keep mine in if it's even remotely light outside, regardless of the weather. if i'm even a little bit late openning their door they are quite willing to remind me LOL. but then again, i don't keep food/water in the coop, just water in the run, and i feed outside the run. i free range them so basically food is just a snack a couple times a day to do a head count.
