Has anyone ever used a yosoo to hatch eggs? I have them in my little giant but would like to move them on day 18 when I remove them from the turner . I teach preschool and I am looking to give the kids a better view of the hatch. I have it set up and it holds perfect temp and I see lots of humidity . My concern is the water tray around the edge. Isn't this dangerous for the chicks? Thanks for any advice!
