PDF?/Cartoon showing measuring the bones of the vent....

[kristen_s]

Hiya!
Earlier this fall, I was trying to work out if I had roosters or hens and someone sent me to a cartoon of how to measure the distance between bones on a chicken's vent to determine if it was laying or not. I'd like to share that with a friend and CAN NOT find it. Help, please!
Thank you!

Here are a few I found. Four fingers does seem excessive, especially for smaller chickens. I think I learned 3+ fingers meant laying and 1-2 not, but maybe I'm forgetting.
