I don't candle mine. My book says 5th-7th day, then 12th, 19th, 24th. This is in the incubating section.Thanks for the advice!! Appreciate it! Now we wait....one more question - - do you all candle like I've read people that use incubators candle or do you just wait it out and see? Thanks! I heard that if you are going to it should be at 10 days for ducks?
I think that if you are sure eggs are fertile, making sure that the hen doesn't have too many under her is more important. You can mark the eggs with a sharpie that are under her and remove the older ones if she continues to lay. Remove any that are very small, very dirty or oddly shaped as they have less a chance of hatching. I'm not sure if bantams are the same but most duck breeds can cover 8-14. I'd go on the lower side for a first time.
Congrats.
