Float or sink? HELP!

[butterflygrooves]

I need to check if 9 eggs are good and want to use the float or sink method but don't remember which mean good egg and which means bad. Can someone tell me which is which?

Also, I let my broody hen sit on these eggs for 4 days (2 eggs on day 1, 4 eggs on day 2, 7 eggs on day 3, 9 eggs today), should I toss them just to be safe? The temps have been around 100 with no humidity and she has been on and off the eggs.

Sink good, float bad. float means air has gotten in and that is generally not good.

I would. Unless you know FOR SURE which eggs came from today. Those 4 day olds will probably already have a very very limited amount of development to them and may even have veins.
