I finally got the system in a couple months ago. My chickens were about 20 weeks old and were extremely curious as I was installing.....tried to "help" me by jumping on my tool box and getting in my way. After getting it up, I just sat on my little work stool and tapped the water nipples, after a few minutes or so, a couple came over to see what was going on. As soon as I left, the same ones checked out the new "thing" in their run and all were drinking from them by the end of the day. I left the old watering container in the run for a couple of days to make sure everyone knew about the nipples. Then removed it. Have had no problems.
One of the best things I have installed and has saved me a lot of work. Love the nipple watering system!!
Good Luck
