I am on day 20 of incubation of my quail eggs and I have had none hatch so far. This is my first ever incubation and I have made sure to keep the humidity and temp. perfect the whole time. On my incubator I can control the temp. and somewhat the humidity but I've kept a close eye on it. I cant really see into the incubator so its hard for me to keep a eye on them. Should I wait a little longer and see if they hatch or possibly candle or float them to see if they are still viable?
