I posted this somwhere else. But got no response. This is my first hatch of cortunix quail eggs. This is 15th day. There is nothing going on in there . NOt even a chirp. Is that normal. I thought i would of seen or heard something by now. I cant candle them . I cant see inside. I got them shipped in from a breeder. So the fertility should be ok. When i hatch chickens i can hear them chirpping in the egg. But this there is nothing. Is this normal. ?When should i expected something? DO you hear them first. Or just a pip?
