Hello everyone! I'm giving the water cups a try. Just put my 6+ wk old chicks into their coop, in the garage with a heat lamp for the first time tonight (still getting below freezing outdoors here, will need to stay put out of the elements for a few more weeks yet but just too big and messy to keep in my living room in a plastic tub anymore!). I placed the new bucket with the water cups in there. They took to drinking out of the cups great but either don't get it or are too small yet to "push down" on the yellow knob to get more water to fill the cup. Anyone else use these and at what age did they seem to be independent with it? I'm going down every hour right now to "fill the cups" for them and am going to place their old waterer back in until the catch on but just wondering how long that might take. They are horribly messy with their other waterer!
