Am waiting on my Xbreed to hatch, it's day 22 now. Timing isn't so much my concern to me, but he PIP'd sometime between 9pm and 1am, 5 1/2-9 hours ago?  Peeping, but no zipping. It's a pretty small egg. He's from a barred rock hen and a bantam roo. Is it possible he's too tight in the egg to zip?  The "sister egg" I have, some cross, is on day 21 and almost a third bigger thn his egg. 
Should I even be worried?
