Here is another book Raising The Home Duck Flock by Dave Holderraed. It was published in 1978! It's pretty much like Storey's Guide to Raising Ducks but there is less information in it.
The only duck book I have is Storey's Guide to Raising Ducks, which you have. I say it's the best out there! The book helped me pick the right breeds of duck for me, which are Mallards and a Pekin. The book helped me to take care of my ducks, and they are doing really well!
And good luck looking!
