It's not a great incubator, like I said I didn't even think she would hatch. I don't think the climate control was very accurate. I feel horrible she suffered.
I believe it was early. I don't know how long the egg was in the coop, I only removed the eggs bc a neighbors dog had ripped my coop apart and gotten most of the eggs :( I was going to let the hen hatch them. Was in the incubator about 2 weeks.
I had an egg alone in an incubator (wasn't even sure if viable just did it for fun) and it ended up hatching at 2 am out of the blue. I took it from the incubator and into a very warm cushioned "brooder". The baby chick couldn't walk without shaking and falling over and within an hour of hatch...
