I have 6 harlequin eggs due today. I'm pretty sure 2 passed in shell just before lockdown. 1 pipped yesterday and is out this afternoon. One I made a small hole beside the beak as it was internally pipped 24 hours. It now has its own pip hole close by. The one I'm concerned about has pipped all the way at the end, and I mean all the way. I have had to assist chickens in this position before. I do not know when this one pipped. It could have been last night or while I was at work. When should I assist?
