Nice job on the incubator and the hatch. You might want to post exactly how you made your incubator. My only concern here is your video shows you opening the incubator in the middle of a hatch allowing the warm, moist air to escape the incubator. This allows cooler, drier, air to infiltrate the incubator at a rapid rate. As you may know this puts the unhatched eggs at risk of drying out inside and being unable to hatch on there own. Someone else watching your video may think opening the incubator during hatching is ok and then loose a substantial part of their hatch. Obviously you lucked out and it didn't effect yours.
