OK, LOL you have convinced me. WHere did you buy your girls-- or do you have boys too??
I got them from Al's Quackery. Unsure if she's still on BYC, I think her name was LearyCow... but she's on FB as Al's Quackery. I think she's near Saco. I ended up hatching 4 boys and 1 girl. I have 2 boys and 1 girl left from that original hatch, but one of the boys isn't a pekin. All of my ducklings and other grown ducks that I hatched from them have met the fox or had another ill fate.
Not too many generations ago there was a diagnosis of "Hysteria," a disorder ONLY attributed to women, diagnosed by men. Treatment cannot be described in this forum, but there is very little doubt the "symptoms" included normal function for a wide - and I mean VERYwide - spectrum of the female population.
With such misdiagnosis, it is not surprising women were having heart attacks totally unnoticed by the medical community, and thus under-reported.
Someone made a movie about this... called Hysteria starring Maggie Gyllenhaal. It was recommended to me on Netflix, so I watched it one night. I was surprised to say the least, but it was good enough to watch to the end.
I've had two heart ablations. Didn't do the trick. Doc says, don't dare go in again, afraid it will just cause more problems than not. They said I had more irregularity going on than they had ever seen. Nice.
