what is the probablity all of my eggs will hatch on day 21?

[farm girl 2003]

I am new to BYC,but I was wondering what's the %rate that all of my chicks will hatch on day 21. My humidity is 60%- 80%. And heat is about 99.9°F. It will be day 21 of waiting in about 2 hours. Thanks in advance.

I just finished my first hatch, so I am new too. You didn't say what kind of bator you are using. Another thread on BYC recommended 100- 101 for a Styrofoam bator. If that is what you have, it may take a little longer. I hope it goes well for you.

Working on my first hatch as well im on day 8, started with a dozen at 8 now, I know 5 are viable, I believe one has a blood ring(my daughter thinks its veins. And two dark eggs that are nearly impossible to candle ( lucky to see the air cells). Im using the lg still air 9300, ive heard alot of bad reviews but ive got nothing but time a patience to work out its kinks.

It could take up to 3-4 days after your hatch date. How many eggs do you have? Still air? Forced air?
