19 eggs from 9 chickens and 4 ducks?

Ok, so explain this to me. I read an article today in the Boulder Daily Camera on backyard chickens. Seems this lady gets as many as 19 eggs per day, from 9 chickens and 4 ducks. Now I'm not so good at math, but seems to me that that is physically impossible. But if I'm wrong, I'm dying to find out how I can get a flock that produces that well. I can't seem to keep up with egg demand all the sudden and with the loss of one of my girls I'm in worse shape. So go ahead, explain it to me

 

Well, that's what I thought, but I can't help but hope.

I'm really hoping it's a typo, because I'd hate to think that this lady is teaching classes on chickens and really thinks that. I'm sure it's a reporter error. But kinda funny.

Actually, it's a really funny article, seems the people down the street from her, got into chickens to teach their son where food comes from etc. Now he won't touch an egg. Grosses him out. He'll eat them from the store, but not the backyard.

This lady had to promise her son not to eat the ducks too. She doesn't name the chickens, because they are food but the ducks are her sons.

I can't blame the kid. I remember everytime I'd catch a frog, my mom would say she was going to make frog legs out of it. It was very tramatic for me.
