day 22 no hatch

[Lunafarmchickens]

6 eggs under a broody hen, all have been developing fine. I can see and hear them moving around inside, but its day 22 now, and none have hatched, and none have pipped. I know that they are still alive. What could be the problem?

21 days is just the average and under a broody they can take longer, especially if the weather has been on the cool side. I hope they hatch soon for you - it's so hard to be patient at this stage!
