Still air the temp should be 101-102 taken at the top of the eggs. My temp goes down during hatch too because I open to take out the chicks among other things.
None of that here!! This is a hands ON thread. Seriously though, hands on hatchers do NOT follow the philosophy of not opening the bator at hatch or not helping. That is the whole reason of the thread, to have a space away from the critisism of hands off and the attitude we shouldn't help or someone yelling about the bator being opened. There are many ways and philosophies of hatching that can be successful. Yes, many hatchers will warn you against opening that bator and helping- that's just one method of hatching, not ours...lol but it is one method.
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.
