GOTCHA !!!

i've had two trail cams out at Lincoln State Park where i work.
we had been seeing a white/black hen and this grey looking hen
and also a bob-tail hen. after two weeks i finally got this pic !
still trying on the whiter one. i set one cam up over a dusting spot and the other where we see them daily. have seen some poults in other areas but none with the white hens.

any thoughts on the bob-tail ? it's a new one on me
