well if your tubs have good temps/humidity mom should be fine with her eggs. I am almost thinking about leaving my 2 in with the eggs because after 2 months of work, my incubator is acting up. Lat week all week the temps were perfect 88.3-88.7, not too bad, and in just the last few days it went over 90, and now it won't go above 86.
But your girl is by nature a good mother, and don't be affraid of her being on her eggs for a few hours, or even more than a day.

And most of all Good luck
