Hatching can happen between 19-23 days of incubation,I'll do that then. I'm wondering if they're close enough that they will synchronize. I guess I'll know in 3 weeks. Not sure what I'm going to do if my first candling does not leave a spot for the new egg. Winging this is giving me a bit of anxiety. But I just don't want to miss the opportunity. I only had a couple of her eggs in there and knowing I'd never have anymore I just couldn't waste this one.
they don't all pop out exactly on day 21.
Adding an egg two days 'late' shouldn't be a huge issue.
What incubator are you using?
