Nice video shootin' !!
I've never seen 2 adult bearded hens together before, but had a bearded hen bring her brood through the back yard when her youngins' were about 3/4 grown. 4 young hens had beards about 4" long, and the hen's was around 6". That's as long as a hen's beard was, that I've ever shot/seen, here and back in Michigan.
