I would candle the eggs at least once a week, also i would smell every egg on that occasion. The developing embryos can still die and an exploded stinker-egg in your incubator can ruin the whole batch.For sure you have a point, the eggs are already quite "crowded" but I can see the veins very well and they are going vertically as they should (not floating in a horizontal circle). The air sacs are quite small to my newbie eye. I think they are doing well.
Can't take a photo because I'm using the mobile's light. And a sawn-off medicine bottle. Painted over with beehive paint.
If they are OK now, it's not very likely they would suddenly die before I open the incubator anyway at hatchday-minus-two, correct? I don't have to look again? I would prefer to just let them be since progress seems good.


Keeping my fingers crossed that the other eggs made it through with only some delays. especially the goose and duck eggs I set.
