How long do I wait???

[arbucklemurphy]

I set egg's on the evening of 2/28 and as of today I still have no pips. How long do I wait before I assume they are not going to hatch. I candled them before going into lock down and all were viable but I'm not sure what to do now. Humidity and temp haven't changed and the incubator has not been opened? Please help I'm new to this and not sure what to do.

If your temperature is off, then they will take longer to hatch. I'd give them a few more days.
