Will any more eggs hatch?

[Greener Pastures]

I have a broody chicken sitting on Guinea fowl eggs. One egg hatched on the night on day 25 and another on day 26. It's now day 28 and there have been no more hatches or pips. I candles a few. One egg has the air sac on the pointy end and some are I think not viable. Is there much chance any more will hatch? Should I do a intervene with the one with the air sac at the wrong end or do a rescue hole? Any advice would be much appreciated.

They could. They can go up to 28 days. If it has been very cool then they could be delayed but not likely since some hatched days ago.
Is the hen still sitting tight?
Were these eggs shipped? I wonder how the air sac end up on the wrong end?
Where are you located?

I got them from a local breeder so they weren't shipped. The hen has been very good barely leaving the nest, even to eat. I am in Australia. It's the middle of summer so it's been very hot.
