Sometimes hatching coturnix quail they hatch over a 2 day period!! Right?? Ok so everyone says dont open the bator if there is pipped eggs because of moisture loss. Well listen to me. I only started hatching 2 years ago. But i must be an expert now. By listening to some of your comments! I pull babies out every few hours and no shrink wrap. But what alot of you say that is a tragic mistake. And i use a mini fridge homemade bator. So i am opening the whole side for up to a couple minutes!!!!!! The trick is!!! With my mighty skills, i ad hot tap water to the water bowl. Not alot just a few ounces. In a small bowl. And guess what??? My majic powers make the humidity jump right back up in minutes!!! They wont dry out in 5 minutes!!! Wow i must have discovered a super power. Because i started this from the first time i incubated with my HOMEMADE $50 incubator. And i always get great hatches. Got one going on now. 100 EGGS IN THERE. And i pull out the babies every few hours. Now im down to 10 eggs. On second day and most are pipping. Not a super power you say??? Well i dont see anyone else making this suggestion!!! And it works great!!
