Now this batch had an incubator issues, so they were without power for 8 or more hours. I was expecting them to hatch day 18 or 19, because of the temp issue. Well 5 of the 6 had pips on day 17, but nothing more by this morning, day 19. So it was time, again, to assist the hatch. I opened them all up. Several were just in the wrong position, and several of the eggs had an unbelievably think inner membrane. I was convinced that none of them would have made it out on their own. I usually discard the eggs that have no pips, but I decided to open this one carefully. Low and behold, a very healthy chick popped out So it looks like I got 5 white Japanese and 1 wild Japanese Jumbo. I think I will take a small break on hatching out more quail for now. I am incubating Yocohama chickens, and I am running out of brooder space. So when is a good age to add the chicks in with other quail?
