Even better yet is using barocca in the the chicks water (Yes I know it sounds strange). Works miracles on weak chicks with leg problems!

Yeah i would get a hydrometer. Humidity does go up when they start hatching i find it does even more so with quails than chickens. I think Bunnings sell reasonable prices Hydrometers. Do you open the vents when they start to hatch? I am not familiar with that type of bator though but if it has vents i would open at least one when they start to hatch. I think you have done well with posted eggs. I hope you have a great hatch with your own eggs as well. You could also try adding some infant vitamins with out iron or a tiny bit of Vegemite to the water should help any weak chicks.
Adorable
