Chic Making Noise in Incubator

Yes this is quite normal for you to hear them in the incubator. The chick or chicks will have pipped into the air cell at the top of the egg and are now learning to breath air. If they were under a broody mum she would be chirping back at them. Bantams can sometimes hatch a little sooner than large fowl. I hatched some polish bantams last week and the first three hatched on day 20. Your chicks will do there external pip on the shell when the oxygen becomes low and the Co2 becomes high in the air cell they will pip a small hole or even just a crack in the shell to allow more oxygen in. They may then rest for upto 24 hours before zipping and hatching. Wishing you the very best of luck with your hatch

 

Congratulations.

 

Hatching takes a long time the chick has a lot of things to do, it has to absorb the yolk sac and all the blood vessels it's also very tiring for it so it will also do a lot of resting. How long is it now since you saw the pip on it? Sometimes they can take 24 hours to hatch from making the original pip hole. Patience really is a virtue with hatching you can't rush it. Your humidity sounds fine at 65%.
