I have 111 bobwhite quail in the incubator. Some of them pipped 36 hours ago, most of them pipped 12-24 hours ago and then nothing. I don't hear peeping and there is no movement. What is going on??? I added extra water to the incubator on lockdown and haven't opened it at all. I did notice a drop in humidity yesterday so I added more water through the vent hole on top. I've been leaving the vent closed to keep in the humidity. I'm so nervous that they'll all died! HELP!!!
