Yay! I can't wait to see baby pics. I am not qualified to give advice, but advice given to me was don't open that bator until those chicks are all dry and fluffy-not matter what. Of course, I never listened LOL. Do as I say not as I do! Good luck!!!
I have read differing opinions on opening the bator. I have a second bator up and going for transferring chicks into after they are mostly dry. That way the new chicks leave those eggs and babies alone while they pip and unzip. That is my plan anyway.
I've heard this works well. I guess once you find a system that works for you, you've got to stick to it. I hope it works wonderfully and produces lots of chicks!!!!
