I am in need of a watering system for 10 chickens. I like the idea of the little cups attached to 5 gallon bucket they appear like they would stay cleaner is this accurate? How hard is it to get them to use it right now they are just a couple weeks old but they aren't as easy to tame as I was hoping they'd be. I am wondering if instead of the 5 gal bucket if I could use a clear storage tote (so I and whoever is chicken babysitting can easily see the water level is good without disturbing the while things). Or would a clear container more easily grow algae etc vs a 5 gal bucket? Also will a duck use the little cups as well? I am less concerned with them as they have a regularly cleaned out baby pool of water and they too did not tame down (even after raising them in my home for the first 2 months of their lives :|). And if the cups work which brand is best? I also looked at different options like the ones pictured. I also no not have electricity to the coop for keeping water thawed in winter and have to carry the refill water from the nearest hydrant that is not very close.
