I got home today to realize that my incubator lid was slightly off. The cord has a habit of catching in the gap and not closing right. I left at 10:30 AM and it was a little before 10:30 PM when I checked on it again. (Work and school, had just gotten home) Is the chick dead? I put the lid on correctly now, but I'm not sure if it's a waste of time. There's only 1 guinea egg in the bator, and it's been in for a few weeks. Also, will that kill the incubators heat making parts? It's a Brinsea Octagon 20 Advance. How do I get it to beep if the temperature drops too far or spikes?
