These are my first duck eggs in the bator one pipped last night at 8:00pm it is now 11 am and still no baby duck. It is rolling around and everyonce in a while I see it pushing on the hole it already made. My humidity is about 55-60 I had it higher but now that it pipped all of a sudden it seems to drop a little is that normal and how long will it take for the duck to hatch.
