Trying to keep track of hatching quail is impossible, they all hatch at once, use a separate incubator per batch if it is important, with 90+ eggs, good luck, I can’t manage a dozen! There are not breeds of quail, just colors and species (bobwhite, coturnix), you’ll be able to get a good idea on color by 3-4 weeks, all yellow chicks with a dot on their head will be your white birds. I’d candle your eggs and check air cells, they might be hard to see but if thy are mobile or wonky looking (or get more wonky looking as they grow), just in case you have shipping trauma, it is best to prepare your expectations now. My two shipped hatches this year had saddled air cells and dismal hatch rates, nothing you can do but hope for the best and prepare for the worst, but if air cells look good, yay! Day 4/5 is a good day to check fertility, a dark reddish black spot with the occasional vein or embryo is a good sign, a yellow/green egg with a faint yolk shadow is usually infertile. Day 10/11 is good for a recheck, veins appear in most eggs and all fertile eggs should be mostly dark. Make sure your turner works for quail eggs. Humidity isn’t a big issue until you hit lockdown. Have fun but remember they are addicting! Also be ready for 87 chicks, sometimes your hatch rates are ridiculously good too!
