They are super cute Sorry to hear you lost your first pipped.
They could be a little later than the others, has anything else pipped in your remaining 6 yet? They all don't pip at the same time. Would be so much easier if they did!! Have you had an even temp around your incubator? Still air or fan? Cooler spots could cause a slight delay in hatch.
I had trouble candling the eggs as they're mottled. I will leave them in tonight and see if there are any signs in the morning. I didn't candle them from the start so they could potentially be infertile. However I did see 1 rock slightly
Ok I just took the eggs out and cracked them. All infertile no growth atall. I am pretty pleased with my homemade incubator. 5 eggs hatched out of 6 fertile ones. I'm going to order another dozen and set them I think.
