Good Morning everyone, I am thinking of making a watering system using nipples for my 21 chickens. In the past, I have always just kept a bucket of water out for them, but am looking for a cleaner easier solution. I read the previous posts on the forum, but am still a little hesitant about which nipple to select. Is there anyone who has had a watering system in use for more than a year with no complaints about their nipples? Recommendations on which to get or which not to and why would be helpful. The system will have a large bucket outside the coop with PVC piping going into the coop with the nipples mounted in the PVC pipe. Thanks in advance.
