Hi guys! I'm a new member here. Ive raised chickens off and on for the past 50 years. This is a first for me in all these years:

Hello, and welcome to BYC. Sometimes a dominant hen fights the rooster, loses the fight, and then becomes a target. It can progress to the point that the hen is killed.

I have a 3 or 4 year old rooster, my ladies are 2 years older.. he has focused on 1 hen! He keeps jumping on her every chance he gets. She runs from him and if outside, she hides, away from the others. (I've got 5 old hens) am planning on replacing these with new hens as the old ones pass.
The poor hen is aggressive to my guineas as well as the 5 chickens that are now 5 months old. All the other chickens leave them alone. So I keep the young ones separated at night until I need to keep them all inside when the snow flies. I have 2 5×10 foot stalls, so not an issue to keep them separated. But why is my roo so focused on this one hen!

Welcome to BYC! It's nice to meet you.
I have the same problem, the roo just likes the hen more than the others.
Anyway, have fun here!

Welcome. It can be so many things that attracts a roo to a certain hen. Roosters are very deep intellectually. They spend a lot of time observing. Colors, thoughtfulness, love in taking care of chicks or physical characteristics of hens make them more attractive to roosters.
