beards on easter Eggers

[sóley]

so I have 5 easter egger girls and one rooster, the rooster is bearded and 2 of my girls to, the other 2 girls are not bearded, I am going to try breeding only easter Eggers with beards but these 3 unbearded are so beautiful in color.
so I was wondering, do the chick get beard if only the father is bearded, or do both parents have to be bearded?
here's a picture of the rooster when he was younger

Chicks may or may not be bearded.

It's all in the genes. I bred an EE with a beard to a BO hen and their son had a beard. The son (Reno) was the only one who hatched so it would take more tries to fully understand beard genetics for me. My guess though would be 50/50 depending on the parents genes.
