I know it is frustrating. I've got a pied female that I bred this year and documented 20 locks. This is her third year breeding and she still hasn't produced. Sometimes, you just strike out.
As for me, I'm not giving up on my pied female. I've got a few other pieds that did produce and I'll try her again next year. I'm not giving up yet. You only have one year in with this female. Give her a break and try again next year.
Good luck!
