And also, Some need the help, with calls it's an all new ball game, That's why it's called the CALL DUCK CHALLENGE, because they are Definitely a challenge to hatch. I can't tell you HOW MANY eggs, I went through before I got it right. OMG, SOOOOO MANY. and like I said before the 10 I lost with 80% humidity was part of that MANY. LOL As far as opening the bator, well, I have a different theory on that. You see I did an experiment I opened the bator during lockdown, I opened it Three times a day as if I was still turning my eggs, I didn't raise the humidity it stayed 50-55 from day ONE to hatching day. Guess what, wasn't anything different. Still had a good hatching, nothing shrinked wrapped, nothing got sticky, nothing struggled. Lockdown was Created by us for the SOLE purpose of reminding us DON"T TOUCH. is it really necessary well that's debatable.
