Typically, koi eggs will hatch in less than a week. Koi eggs are very small, bead-like specks that can vary from milky white to yellow or green. Upon closer inspection, you can see two black dots through the transparent membrane of the egg. These are the developing eyes of the koi.
How long does it take for pekin eggs to hatch. I have pekin eggs incubating for 21 day today. I candled them and can see air pockets and veins in them but no of them seem to be hatching yet. How long more should I wait or what should I do next. Thank you in advance.
