Argh! I have to make my decisions!!!! And what’s the max number you would personally try?I'm so glad she's a chill broody! That's a good sign! I personally would give her as many chicks as you plan on having her raise all at once. The one time I waited a bit longer to give another chick, out of the 3 broodies, none of them would accept the straggler.
I figured she would be chill.... my last round of “culls” to the layer flock was when I rehomed every single layer that even looked at the 3 week old meat birds wrong. It left me with only five, but I’ve got backups growing out!
