Bubbles ??

[TheBajan]

I am on day 6 1/2 and I just candled my eggs. One of them appears to have bubbles in it. They definitely float as i rotate the egg. Is this a viable egg or should I toss it? Out of 36, 11 are clearly developing. One has bubbles. The remaining 24 I simply cannot tell. One of them I was unable to even see an air sac but the rest have air sacs of varying sizes. Should I candle again in 3 days or wait until day 14? I don't want any exploding eggs as that sounds pretty awful. Someone said not to toss any of them until day 10 so I'm not sure how urgent the iffy ones are.

Bad egg, I'd get rid of it.

What about the others? Should I candle them again on day 10 or should I wait till day 14? With 24 of them I'm just not sure so I don't want to toss them yet but I don't want to wait too long and have exploding eggs. I'm too inexperienced to tell if they are viable. Does the size of the air sac tell you anything?
