Hello. So this is my first time trying to hatch eggs with an incubator. I bought my incubator online. It has digital heat/humidity, and auto rotator. We had 12 eggs in it. On day 18, before lock down, 6 eggs didn't develop. The other 6 seemed to be on track. We've kept the temp at 37.5-37.7°C the whole time, and moved the humidity up to 65° on day 18. Today marks day 22 and no hatching, chirping, or pipping yet. Is it likely these 6 didn't make it, or should I leave them for a bit yet?
