I'm looking to hatch ducks in spring, but I'd like to know if my drake is mating her. The breeds are: Mallard hen (She's a runt so she's very small) And a Pekin drake. She tries to get him to mate her but he never does, at least, not what I can tell from. I found this article and found it interesting, but not sure if it works. https://www.selfsufficientculture.c...gs-are-fertile-or-not-quail-chicken-duck.533/. I tried the trick and it was the apparent "fertile" I don't have an incubator so I can't try to incubate some eggs and see if they develop. The eggs are going to some family members so I'm trying to resist checking for the bulls eye in the egg, well, if it ihas that. So is there any other way to tell if they're fertile?
