Seems to be two schools of thought on this at BYC and it all comes down to personal preference and the best way to manage your own flock/coop/run setup. I chose to only provide water in the run. Feed and water in the coop. I saw so many posts from folks who were having trouble getting the youngsters to go up/down the ramp and put themselves to bed at night when they first went into the coop. I reasoned keeping their food in the coop would provide a good motivation for going in there throughout the day and at bedtime. (I also provided a light) Maybe it was luck or coincidence, but I can tell you that I only had to put my 5 week old girls back into the coop on the first night they were released to the run. Thereafter, they did it themselves. Feed in the coop only solved a couple other issues for me, too...keeping feed dry and not attracting mice/rats/squirrels to get inside the run at night.
