Good luck! I've tried high humidity, low humidity, ??? humidity, asking what is considered high/low - it's been pretty much a crap shoot. Several batches none hatched. 7 from one batch (4 doz eggs) and 5 from another (3 dozen eggs). NO duck eggs yet to hatch despite plenty of consistent temps, humidity, broody or bator, looked fertile etc...so still trying to figure it out and "the book" does not tell everything. Last batch (the 5) I had a few others that pipped but didn't hatch...almost every one had a chick in it - but aren't hatching!
Shipped eggs, local eggs, eggs from the back yard - doesn't make a difference.
