I'm looking for the best breed of ducks for setting. I just want one that will set. I have a pair of pekins (Jake and Emma), now Emma lays every day and I tried to let her set in Sept. but she wouldn't stay on the eggs. They were her first eggs and she was only 7 months old. These are my first ducks and I love them dearly and want more. Was that to young to expect her set. I have my heart set on some runners and calls in the spring. I appreciate any info I can get on them.
