I have one of those red plastic rectangular feeders. I screwed the bottom of it to the flat side of a 2x4 as soon as they could reach, maybe a week old. Now they are almost 7 weeks and it is still working well as the second feeder, for the ones who get bullied away from the big one. Waterers I just set on bricks or something -- if the waterer is set on something big enough for them to stand on, the water stays clean longer (well, half a day....)
