I incubated 4 eggs back in June, all 4 made it to lockdown, but one never did pip externally or internally, so unfortunately it didn't make it. But I noticed after time the air cell got bigger and there were bumps all around, it wasn't a straight line. Not sure if there was anything I could do, I gave it time and didn't assist. I believe it died the first day of lockdown or so.
It started looking really weird and abnormal. That wouldn’t happen with a live chick. That was day 21.
