The earliest a pullet went broody...

My serial broody Peach had a daughter this March, Kiwi. Kiwi is 5 months old now, laid 15 eggs and now she's broody lol. What is the youngest broody you ever had? Did I set a record?

Wow! That is young.
But since Kiwi is Peach’s offspring that makes perfect sense for her to be broody.

One of my hens sunny , went broody at 6 months after laying 5 eggs . Since march she has gone broody twice a month ! The one time I let her sit she leaves the eggs on day eleven ! She is a Cochin bantam tho .

You could start lending them out or start a “rent-a-broody” business.

Hope Kiwi is as good as her mother. There is no space for bad moms on my flock!
Peach is an easter egger araucana/faverolle
Kiwi is araucana/faverolle/legbar

Kiwi:

Mom, dad, and Kiwi

That's young!

My youngest brooder was four months old when she went broody for the first time. She was this Olive Egger who I'd say had some hormonal issues because when she wasn't brooding all the time, she was mounting the other hens like she was a rooster. On the mounting, it got so bad I had to put saddles on my girls even though I didn't have a rooster.
