Clearly, the bluish egg signals that the left side hen has finished laying her clutch. But the right side hen is still laying. Usually, we set when the bluish egg is laid so Sandy wants to know if we set her or wait?
I like to give laying hens Avi-Tech calicum in the water while the hens are laying. I also like both hens to hatch the same day, so both have chicks to feed on the same day. So that means we will hold the left side hens a day or two to wait for the other hen. I will rotate the eggs making sure the small end is up to ensure the egg membrane where the chick pips stays moist.
