Sixty knots is about 69 MPH. CVN-65 was capable of blowing the doors off every surface warship in the world, including a Nimitz-class carrier. I don't mean faster, I mean significantly, markedly faster in speed and acceleration. And she couldn't make 60 knots.
If for some reason the temperature has dropped below the correct temperature on a few occasions, you could find some of your eggs only hatching on day 22, 23, or even on day 24 or 25. Whereas fertilized chicken eggs usually take exactly 21 days to hatch, most duck eggs take 28 days, apart from Muscovy ducks.As a general rule of thumb, the eggs of Muscovy ducks take 35 days, but once again, it can vary slightly depending on conditions.f on the other hand you use an incubator in order to hatch fertilized chicken eggs, they can sometimes hatch a day or two early, or they can also hatch out a few days late. Things like humidity and temperature play a significant role.
So, how long does it take for fertilized chicken eggs to hatch? The answer to that is 21 days exactly, although you need to bear in mind that this can vary, depending on a number of circumstances.
