Every day, student helpers turn the eggs over just as a mother hen does in her nest when she is setting on eggs. Once in a while we use a bright flashlight to candle the eggs. That means we hold the light up to the shell to see the embryo inside. We have seen some of the embryos moving around inside their eggs, and they are definitely getting bigger!
Since chicken eggs hatch after about 21 days of incubation, we are expecting our new babies around May 13. (Guinea fowl eggs tend to be trickier to hatch, and they take 28 days, so we are hoping to welcome a few additional baby chicks on May 20 if all goes well. We can't see the guinea embryos through the thicker eggshells, so we are just hoping for the best.)
Thank you Mrs. Ploeckelman (Miss Ploeckelman's mom) for supplying us with eggs from the farm :)
