How do I tell which is rotten?

[SnazzyJazzy]

I have a rotten egg, well at least one. I can tell by the smell in my bator. Problem is, how do I tell which one? I have some that are ten days old and some that are almost three days old. None look weepy. I will be tossing any of the clear ten day olds, but what if it's the three day olds? These are Guinea eggs and the ten day olds had pretty obvious development at 3 days. But I did have a few I had assumed clear turn into a developing baby at day 7.

I had this problem and picked up the individual eggs and sniffed them. It was pretty obvious which one was bad.

Where did you get the eggs before you put them in the incubator? It shouldn't be rotten by 3 days. Candle the 10 day eggs, you should be able to see which ones are good and which ones aren't.

Definitely could! It was leaky on the bottom and the smell about knocked you over. I removed the obvious 10 day clears and two blood ring. Sadly I tossed a bunch, but that's the risk, especially with shipped eggs.
