I must have messed something up during my last hatch to have gotten as many bloody umbilicals as I did. The humidity level was at 70% the whole time dropping down to 65% a few times when the water level got low.

So, what SHOULD it be?

in the 40% range for incubation; 65-72% for lockdown....and the lockdown humidity can get as high as 80+% as the eggs hatch and add their own moisture to the mix.

I'll try for 65% during the next lockdown instead of 70%. My hydrometer was calibrated so it wasn't off. I'm pretty sure the humidity level in my first batch was the same as the bloody umbilical hatch and the first ones were fine. I'm not 100% convinced it was humidity levels. I had several different variations of Wheaten Ameraucana chicks. Wheaten/blue wheaten/splash and the ones with the blood umbilicals were all yellow chicks. The white and splash were all fine. SO....... I'll try again. So far the chicks are doing fine.

Oh got it. Well here's my dilemma. I had a chick this evening that I had to help hatch because the egg shell got stuck to it, but it had a bloody umbilical cord. So is the humidity too high or too low? I'm confused
