Questions on hatchng chicken eggs

[TSW99]

I put my chicken eggs in my incubator on September first. They are in one of those cheap Little Giant incubators with the eggs being nearly 19 days old I'm worried about the chicks not having enough air?
the eggs are on lock down now. any suggestions on what I should do when they hatch. this is my first hatch of my own eggs so I'm learning.

What is it that makes you think the chicks won't have enough air? If there wasn't enough air your eggs would not have developed. They need oxygen to develop. I'm sure your incubator has vents and or holes to let the air in. I would really try not to worry incubating is both nerve racking and exciting all rolled into one. Good luck with your hatch

Ok thanks I didn't think those little holes in the top were enough
