As above, I know you lot probably sick of hearing this as I've been through most if not all threads on here regarding late hatches. Right now I'm on day 23 going into 24. I've sulmtaler bantam eggs in and a black japanese in a hatcher at mo. They needed lockdown 4 days before my other batch so I fired up my spare incubator set it to hatching conditions/lockdown. Day 20 black jap egg wiggling mental most others were not. Hatch day up till now NO movement, or pips in any of the eggs. BUT today to be on safe side, I candled the jap egg and a sulmtaler (all under strict humid conditions as I was scared stiff I'd shrink wrap them had they internally piped. Anyway, both eggs I checked full and very much alive and hopefully well. I couldn't see an internal pip but I'm unsure what to look for, I saw the japanese right at the edge of the air cell but not IN it, the air cell was fluttering if you know what I mean? Is this internal pip then no? All back in bator but I'm stumped to know why they're SOO late, this is my 5th hatch with latest being day 22. I know the temps effect this but I had no issue temp wise, only humidity high in the day never above 60 tho if it went up near 60% I let some hum out! then it was low at night no lower than 40%. Any input greatly appreciated folks, the internal pip has me stumped tbh as I saw no beak as such just the flutter.
