I candled my first batch every day till day seven. I think I'm just gonna candle at 7/14 next weekend. I was really able to see which egg of the first six was clear compared to the others at that stage, and confident enough that it wasn't just a slow developer. But then again I'm new to incubating and candling so I still need to develop an eye for a good egg vs. bad egg.
