I have a group of 2 hens with 18 young, and 1 hen with 5 young roaming around my place in Cocolalla.   Definitely more than what I saw last year, but I have only been here a couple years so I don't have much data to go on.
It was a much dryer spring than last year which I would assume has some impact.  
Saw these three on August 30th last year!  very late hatch for sure.  Pretty sure they did not make it.
