Apologies; I know this has been asked before, but I have some specific questions not addressed in other threads. I have been using these waterers from TSC: http://www.tractorsupply.com/en/store/harris-farms-poultry-drinker-35-gal-capacity?cm_vc=-10005 I like them because they are lightweight, easy to clean, easy to fill, and the ice slides out of them easily (VERY important to me this time of year). However, my waterers both failed within the past month. Small cracks developed on the top of the waterer, which of course allowed air into the waterer and all the water leaked out without my noticing. That meant that twice I had chickens without water and had to do a total clean out of the hen house because of the water-soaked bedding. That also cost me money because of all the bedding I had to buy that I didn't expect. The second one failed just yesterday, so I need to buy new waterers ASAP. Here's what I'm looking for: 1. Can be hung by a sturdy hanger 2. At least 3 gallons 3. Easy to clean 4. Easy to fill 5. Ice slides out easily 6. Less likely to fail Anyone have any ideas? TSC also sells this waterer http://www.tractorsupply.com/en/store/harris-farms-double-wall-drinker-5-gal-capacity?cm_vc=-10005 but something about it makes me nervous--it looks difficult to use, easy to bend out of shape so it doesn't work, etc. Also, reviews said it rusted and it's very expensive compared to the plastic--but maybe you've had a difference experience with metal waterers over time? Waterers are so expensive and I'll need to buy at least two of them this weekend. Many thanks!
