I have a cube with the feeders and drinkers. I have two feeders, which work well for my five hens. I don't think they are as keen on the drinkers, as they tap tap at the nipples to get the water out and I get the impression they want a bigger drink. I keep it topped up but provide a litre bowl of water too that gets finished each day. To be honest I've been thinking about replacing it with a hanging water reservoir.
