I'm on my second hatch with a new incubator (Brinsea Maxi 24). Loved it the first time we used it. But this time I'm having issues with the external room temp alarm going off the past three nights. It's gotten down to about 62F in the house overnight. We heat with fireplaces that I'm not comfortable leaving unattended overnight and I'm worried about the eggs. Any suggestions? I don't have a warmer room to move it to. We are 15 days into incubation. What would be a safe way to insulate it? Thanks so much.
