I have one that pipped last night between 8-10 pm... it's still not making any progress. I also had one pip earlier today, and it was out within 20 minutes! The one thats hatched out is a strong chick. I'm amazed at how awake it is already. The egg from last night has blood by the cracks in the shell. I hope it makes it... but I dont think it's quite ready to zip yet. I have 2 more pipped eggs now. They appear to be slow pokes too.
