Hi everyone, I have a JN2-60 Incubator, I got it from a friend and this is my first time using it. Its half way through day 21 of the process and nothing has piped yet, a bit of movement the last few days (rocking etc), from what Ive read I'm not too worried. My question is now that its passed the 21 days do I add more water to the bottom trays to compensate for the additional days?
