there's really no reason to keep food and water in the coop at night, after all they go in at night to roost
not to eat and drink and if yours are like mine they eat,drink and forage alllll day long.. then thorughout the day enter
the coop to lay eggs then back out again to do more eating,drinking and foraging. the only time I will put water and food
in the coop is dead of winter my ladies refuse to come out if there's more then 3 inches of snow on the ground last year they stayed
in the coop 3 days straight so needless to say I made sure they had plenty of food and water under those circumstances..
Mine tend to like that last minute bite before going to bed for the night . For that reason I do keep a small amount of food for them in their coop. Their main water source is in their coop at all times. I won't keep food in their run at night. Too tempting for rodents. During the day I keep their food in the run for them. During the warm months anyway. Winter time, both stay in their coop. Our winters are long, cold, and hopefully full of snow. (Got jipped for snow last year.) =(
