Oxygen/humidity in lockdown

[MrChicken54]

So I have a couple questions:
1) In the attached pictures, will the chicks be able to breath as they hatch? Will enough air flow get through?
2) I can't get the humidity in the second incubator over 50%. Is that ok? Should I try harder? I've read anything from not over 55% for lockdown or they'll drown, but at the same time I've heard that it needs to be at 80% or they'll dry up--although I know that 80% is way too high. The reason I can't (as you can sort of see) is because I put the light bulb in wrong and it melted a large hole in the top, so all of the humidity escapes. If I put something over it, then it will get too hot, so I'm struggling with my second one. However, my first one is perfect (68ish%).

Also, the second incubator was at 95 degrees last night for a couple hours. Is that ok? It's day 19/20 today and I'm trying my hardest but things keep going wrong with that incubator

You could increase the humidity by putting in a sponge. The amount of wet surface area is what increases the humidity, so anything that has a large wet surface should help you get the bump you need. As for the cooling, I'm not sure. Update?
