Hi there- I am incubating some chicken eggs, and I have 1 double-yolker. I believe only 1 embryo is developing inside, which means there is an extra yolk in there. I have found plenty of info about 2 chicks in 1 egg, but I would like some advice on helping 1 chick hatch out of an egg with an extra yolk. Can it choke if the yolk bursts? Should I do anything special for this chick to give it a better chance of survival? Thank you!
