Eggs, day 20 pip?

[Lemon12]

It's day 20 here and so far I have one egg pipped, and the rest tweeting away inside! The egg that pipped had pipped around 6 hours ago, but I haven't heard from that egg since - is that fine or should I be worried? Thank you!! X

That all sounds normal. Good luck for a successful hatch.
