Please don't float test them @OroraOra . It's a terrible idea, and I wish it wasn't so popular. It doesn't work. Candling is the only method. You'll know by candling if they're alive. There will either be veins at the top (live egg) or not (dead). Dead eggs look cloudy and confusing. If in doubt leave them. Leave any and all eggs until day 25. Then you can candle and toss the remaining eggs. Always candle before you toss just to check. You can open them up and eggtopsy them if you feel up to it (I always do).
Why do you think water candling is terrible? A few weeks ago I water candled my bantam's 5 eggs a day before the expected hatch and it worked perfectly (it tests for movement not floating). Out of 5 eggs 4 jiggled within a few seconds, the 5th egg did not move and never hatched so it was 100% accurate. I have also seen avian experts use that method which convinced me it was safe.
Also water candling is *only* used very close to the hatch date when candling with a light will only show a "black mass" that denotes a developed chick, but often won't show if the chick is actually moving/alive.
