Oh about 10 years ago, DH looked at kids, looked at the chickens, looked at me, looked at the chickens, looked back at me
"Didn't we start with 3 chickens?"
"Yes dear, why?"
"How many do we have now?"
"Not sure"
"Did we start with ducks?"
"Nope."
"Why do we have them again?"
"They are cute."
"Ok"
Left it at that.
2 years later, he'd heard the term chicken math somewhere. Repeat the looking around at the flock, having now added guineas
"Dear, how many chickens do we have now?"
"More than last time you asked, why?"
"I think you've passed chicken math just fine. I think you are now taking chicken algebra."
"Um, ok dear?"
Now, before I am the one at fault for EVERYTHING...
Then 10 y/o DD goes "Dad, can we get peafowl?"
"What?"
"I want to have some peafowl, I think they are interesting."
"Why?"
"Dad, please??? Here is what they need, what they act like, etc..." as she handed DH a pack she'd printed.
"What did Mom say?"
"To ask you."
DH flipped thru papers "Well, I guess 1 male and 2 females would be ok, but we have to build them a barn and pen first."
Yes, I did tell her to ask DH, as I figured he'd say no.
I think we are aiming for our doctorates in chicken math.
