Because you're using the reptibator I am assuming the tub is not that large, so you may need to burp it every once in a while, maybe once every 2 weeks for a few seconds.

I use larger tubs, and I don't burp them until day 40, then on day 45 and 50. On day 50 I move the eggs into a new tub with coco husk. This is where they will pip and hatch, and that tub has holes so I don't need to burp.

I would recommend adding a very small CPU fan into that reptibator. The thermostat is on the top, so the temp on the bottom will be a degree or more lower and so the fan will help keep the temps uniform.

Goodluck with your clutch!!
