I put 9 bantam eggs on lockdown yesterday morning and noticed last night that one had externally pipped. Got up this morning and no progress on that one and now another has externally pipped. Obviously they are early and I'm not sure how long to give them before I start to try to help. This is my first attempt at hatching. Thanks!

third egg was a small duckling that got pushed to the side of the nest and I found him super cold and put him under mama and he’s alive but has splay leg so I will have to pull him out. Two eggs have turned dark. The last two had pipped holes and one got crushed while he was unzipping, And died and not the second has been crushed but the duckling is alive and yawning. I thought duck mamas did this right lol am I having issues because there is two of them? Can I put this crushed egg in the incubator and would I need to help it hatch when it’s done yawning?
