Hi! I just started with the 5 gallon bucket/water nipples this week and I was SO surprised at how quickly the chickens picked it up. We have 7 that are over a year and 3 that are almost 3 months. I just held a meal worm up to the nipple so they would have to hit the nipple to get the meal worm. After doing this with 3 of the older ones, they got it and showed it to everyone else. In our set up, the buckets set into what was a huge fish tank stand. It is covered on 3 sides, so the buckets themselves stay shaded all day and I covered the lids which see about 4 hrs of sun, with the FarmTek foil stuff that they use for mailers. This kept the water pretty cool, but I found that if I freeze two, 2 Liter bottles (one for each bucket) and put it into the buckets each afternoon the water stays cold...they LOVE it. Then I just freeze the two that were in and repeat the next day. Hope this helps. The water stays clean and cool! I am SO glad that I tried it out!
