I use the Little Giant 11 lb plastic hanging feeder for my 11 chickens. I hang it in the coop from a cup hook and just fill it whenever it needs it....about every couple of days. I was going to make one of the tube feeders but never found a good spot for it in my coop so I just went with this. It is easy, the chickens like it, they just go into the coop to eat and since I switched to pellets from crumbles, don't have any waste by them throwing it on the floor.
You may have to just try a feeder and see how it works for you and your schedule. If it doesn't, then look for something else.
Good luck!
