Pekin ducks aren’t fertile anymore?

[JennyHendley]

Hi, I have a mama and female pekin duck and have successfully hatched for ducklings. However since that last fertile one all the other eggs have not been fertilized? Are they only fertile at certain times?

Have cracked open the eggs to check? Have you seen them mating?

I haven’t cracked any but have left them in the coop under broody hens and candle them after about a week, but the last one that was fertile was July 9. After that none of them have been. I’ve seen them mating a few times.

Crack open an egg in a bowl, look for a white bullseye target on the yolk, if it's just a dot, it not fertilized.
