My DH built my homemade incubator and a separate hatcher (because I got eggs going all the time!). Instead of fiddling with water bowls and sponges, he built a controller and used ultrasonic humidifiers for the humidity. We've had a few mishaps with this design, but overall it works great and the humidity stays constant . . . as long as the water reservoirs are filled! Well with my current hatch, I woke up yesterday morning and the humidifier was out of water and the humidity in my hatcher was 16%!! Ee gads!!!! It had been fine the previous evening but I guess since it's so cold outside and the furnace is running constantly, the humidifier is running way more than it did with my previous hatches. Of course I immediately filled it up and it was soon back where it should be. That was day 19 on my hatch. Do my babies have a chance??? I will be starting day 21 this evening - I don't see any pips but did hear a peep this morning. Humidity is at 68%. If the babies hadn't pipped would there be a chance they were "shrink wrapped"? With having the humidity okay the rest of the time, would the water be replenished in the membranes?? Thanks for any help.
