This will be the 4th year for me to hatch chicks for my classroom. I had a Hova-bator and had very good luck. This year I moved and am using an old hova that is in bad shape. I saw the Top-Hatch incubator. Compare this to the Hova-bator. I only do this once a year but it is important that we have some hatch for the children to explore and learn about. Thanks!
