What could be the problem? I helped a chick hatch and when it open the egg sac was not fully absorbed the yellow jell type thing inside the egg. And the navel is still connected to it and I cut it with a scissor, so far the chick still lives and hoping it will grow normal. I read some post saying it's to much humidity, to much humidity when? During the incubation period or during the lockdown period? I'm a noob in incubation, thanks to many info here so far Im doing good my hatch rate are 65% - 100% and I just started incubating last october. My incubator is stryfoam type that I made, and I don't have any instrument to measure humidity, can't find anything here in our location. How to I know I'm in safe zone in terms in incubation humidity?
