It's ok to continue candling them until you get your first pip. If you can still see some blood vessels, then they probably aren't ready. That first stage of hatch is when they internal pip. You would see a beak moving around in the air sac. How many eggs are there? What day did you set them?the air sac is dark. i can see some blood vessels i suppose,, one pretty big one on the best egg.. is it ok to candle them often? i check about every 2 days to see if theyre moving. they still are!![]()
