I am gathering my equipment and supplies and will soon start to build my own incubator. I have heard tell about these water wigglers/ water weasels, I would like to learn more about them and maybe see a pic or two. Where to get them and exactly where to place and operate them. I do understand the purpose for them, I just have never seen them in use. Thanks for your help. AL many more bator Q's to follow if you don't mind.
