For DIS, no movement whatsoever and there’s also a little discoloration in the fluid just above the chick but under the air cell. I do always leave these though in the incubator until all the other chicks have hatched. Just mark them so I know which one it is. You never know, I could be wrong but so far haven’t been. I candle quickly even under lockdown and have not had any problems doing this. But I also have quite a few years experience. The one that’s behind, you can see shadowing at the bottom of the aircell but no internal PIP.
Sometimes these are just a bit late but sometimes they end up being malpositioned. I make no intervention or do anything whatsoever unless the chick has internally pipped. These eggs are high value and I have customers for all of them that hatch, so I do make safety holes after they’ve internally pipped for about 6 to 8 hours. Does not interfere with their ability to hatch and ensures they have enough oxygen. Many would argue against it, but this is just the way I do it.
