He didn't 'hate' her, he was suggesting dominance/mounting, then backed off because she declined and he's smart. It's good sign.Magnum started out trying to fight Agnes. He'd go up to her and put up sickle feathers by his neck. He hated her.
I presently have a new cockerel(22wks). The other cockerels were removed a month ago, old cock was removed 2 weeks ago. He's slowly winning over the older hens, but they, along with the old cock, had been schooling him since 4 weeks old. Am real happy with him so far, but still a bit leery, we are still feeling each other out. I frequently(2x/day) walk thru the run, making sure he gets out of my way.
But I never handled him much and never cuddled him, handled him off the roost a couple times just so he knew my voice and that 'he wouldn't die' if touched/handled, and touch him often during after dark lock up and head count...always with the soothing voice and calm demeanor. Also pick up pullets during day in front of him; quickly, calmly, confidently, and that voice again telling him it's ok....that is most important IMO, he needs to know that I am not a threat to his flock.
