Can someone answer my question please???^^^^^^^^^^^
You should collect as many as you want to hatch up to 7 -10 days worth and then set them all at once. If you keep adding eggs on different days they will have different hatch date and that will be not good when it comes time to lockdown your eggs.
All will be revealed in time. Moving them around too much to candle and check can do more harm than good. Just put them in and check in 7 days.
