The birds and the bees --- On Giving the "Talk"

I'm a 48 yo GWM at the moment and work in the healthcare field. One of my coworkers, a SBMF with four sons is also a nurse. She had heard that I raise chickens and wanted to know about them. So I told her that I have what I had thought were all hens. Turns out one showed the signs of being a rooster.
"So what does that mean?" she asked.
I told her that it had negative ramifications because (a) I didn't want fertilized eggs and (b) they were illegal pets in my town.
"What's the fertilized egg mean?"
"It means that if you go to crack open an egg for breakfast, instead of finding a white and a yolk you'll see the makings of a new chicken."
"How's that happen?" she asked.
"With the help of the rooster," I told her.
...
She honestly didn't understand ANY of it. THAT was frightening. Beware of you health care providers!
