I wanted to get one of those blue giant barrels (55 gallon?) and add a spout on the bottom (like for were you attach a hose? Don't know the name, lol), so that I can collect rain water for the chickens drinking water. I'm also wanting to do a pvc waterer for the chickens. I have seen the rain barrel done on here somewhere before, but can't quite find it agan. Anyways, the one that I saw had 2 layers of wire to screen out any leaves and whatnot as the rain came in it. It looked really neat, and that's what I'm looking for. DH had a few questions - he's not sold on the idea yet. We live near Tampa, FL, and there's factories and such near us. Lots. He's worried that pollution from the air will be in the rain water and therefor the chickens would be drinking the pollution. Is this a worry? Is there any solution? How easy is it to clean, and how often do you clean? We don't pay a water bill, so it's not to save money, I'd just like to do it so that it helps conserve the water we are using a bit (environmental reasoning) and because I think it would be neat and fun. We'd also use the water for plants in the summer if we have watering restrictions. Anyone have any experiences they want to share about collecting rain water to water the chickens? Thanks!!
