Chicken math is a real thing. You could just count how many chickens you have. But, if you want a more accurate number, you must use chicken math. 

According to this method, I have one chicken.

Chicken Math Explained – Calculating Your True Number of Chickens – Farmhouse Guide

Here’s my version:

• 2016 I had four chickens. Sadly, one got eaten by a fox (Rose). 
• In spring 2019, I got five chicks. One turned out to be a rooster (Gordon) which I rehomed.
• Two more chickens arrived, adopted from a friend.
• In spring 2020, I picked up seven chicks. Five turned out to be roosters that I rehomed. From that batch, the two chickens left both became a fox’s snack. 
• So I bought three more – black ones. 
• But some of the old gals don’t lay anymore, so I purchased another two – red ones this time.
• One of the old girls got sick. We had to put her down (and when I say we, I mean my Dad.)
• One flew the coop, literally, and got eaten by a fox.
• In 2021, I picked up five more chicks, so cute! Two of them (surprise, surprise) turned out to be roosters which I rehomed.
• Then I got four ducks.

 And that, in a nutshell, is the difference between my math and chicken math. I believe the chicken math method is more accurate; seems like I’ve got room for a few more, haha!
