I have a hanging feeder in the coop that will service all of my chickens at one time. I made it out of a 5 gal bucket and 4"pvc. Works great and I can raise it as the chicks get bigger. I also have a nipple watering system with 4 nipples inside the coop. By doing it this way I can leave the chickens in the coop if necessary due to weather. In the run I provide a 1/2 gal jug with one nipple in it for water and no food. I give them their treats every morning in the run. They have access all day to the coop and they do go in and out all day. I used to give them food in a pvc feeder outside but couldn't protect it well enough from the rain and ended up with wet food. I always recommend the nipple system which assures that the chicks have clean drinking water. I had a wall mounted wooden feeder in my brooder and the only thing that I would recommend with that is to make sure it is high enough that they don't billow the food out. They will also sit on it if the trough is too wide. Thus, poop in the food.
