Chicks generally start the hatching process on the 21st day of incubation; this would be (tomorrow) Monday morning.
There is no sign of early “pips” (ie, first breach in the shell) which is probably a good sign. Incubations that run too hot tend to hatch early so I was worried about that due to the temp spike I talked about earlier.
I’m a little surprised how much water the ‘bator is using to stay in teh 70-75% humidity range. I’m having to add 10oz of water 2x/day. Luckily I drilled a hole for food-grade tubing and inject the water through that. When the birds start to hatch the humidity will naturally increase as they air-dry. So I may not have to add as much water to the ‘bator.
