I LOVE this incubator! It's a great incubator for the first-time hatcher! I was a bit nervous about hatching my own eggs, at first, but, as long as I followed the instructions that came with the unit, I and the eggs, were OK! I have to say, even though I've only used this incubator once, so far, I did have a 100% hatch rate! And all the hatchlings are now out in the grow-out coop, happy and healthy! I am very pleased with this product and I highly recommend this for anyone who wants to add a few birds to their flock! I plan on using this unit to replace my birds as they get older or need culling.
