I honestly have no idea why. Both of them have been just fine with everyone up until about a week and half ago. The only thing I can think of is age. I have noticed since hatch with all the English Orps they are very very slow to mature. Perhaps he is just now truly hitting that teenage jerk phase.
I hold hands with the kids when they are going into the chickens territory. After Oreo I was taking no chances and hoped to eliminate any running away or chasing from starting and it was working well.
Then today he went after her while I was holding her hand. I grabbed a tote to block her from him and he flew up and hit that instead of her. No one was injured then he stared her down then walked away.
I am heartbroken, she loves that rooster and doesn’t understand why he is being mean to her.
