New with incubating eggs?

[daniellenoel]

I am a 2nd grade teacher and we have an incubator in the classroom. We are on day 22 with 19 chick eggs, I increased humidity to 65% on day 18 the temp is 99.6... when we last candled the eggs on day 16 all had live embryos. There is nothing happening.... any siggestions??? The class is very curious. I hope we some hatch.
Thanks

By the way

what was your hum% from day to day 18?? around 40% ??

Are your therm and hygrom both accurate??

sometimes it takes a couple of extra days for chickens to hatch..

they are chickens, right?? guinea and ducks take 28 days..

Yes, the farmer who gave us the eggs will be taking them back.

I am using a Brinsea Octagon 20 incubator so I think the tem and humidity are accurate.
From day 18 until now the humidity increased to between 60% and 65%. I added 2 paper towels in the bottom to wick the water.
Yes, they are chicken eggs
