I have read tons of stuff on line and watched a lot of youtube video's on how they are made. But have any of you made one that works really well and how often do you use it. My son and I are thinking about trying to make one, more of a project to just hatch a few chicks. Not going into the business, just think it would be neat to build. If you have made one that works up to your expectations and don't mind sharing the how to and pics, that would be awesome. Thanks everyone who replies.
