This is our first try at hatching, and we've done a HORRIBLE job regulating the temperature in our incubator. It fluctuates from 80 to 104, and I'm afraid we've either frozen or cooked the chicks. Next time I may try to rig a thermostat to help us control the temp. They eggs will be 21 days incubated on Monday, but if they haven't hatched by then, how long should we wait? My second question is how and when to increase the humidity. It's been around 30% up until now, but I understand the chicks need higher than this to soften the shell for pipping. I appreciate any advice!
