Yes - in the Fall you should see a dramatic change. I didn't want a Roo after the trouble with mine, but I am glad for the Enablers for my chance to give Mr P a good home. He is very quiet, sensible, the girls absolutely love him, they all groom him and they all trust him. There is NO drama at all in the barn, no hens are running away from him in terror.So far, the kids (3 & 6) have been completely exempt from his ire. I monitor that very closely. Today, DD and I went out to collect eggs and Oreo came into the coop to see what we were up to. My daughter did a great job just continuing on and slowly and steadily checking boxes while never turning her back on him and I stood stock still by the door ready to intervene if the need arose. He stood and watched her for a minute or two and looked me up and down a few times and then left to go back out to the run even with a few pullets still in with us. No aggression no drama at all. I find this promising. Some trust remains in his hormonal brain, I just need to build on that.
I will give him time space and all the treats to give to his girls. Hopefully hormonal idiocy will wane and he will learn that although there are indeed threats out there we aren’t one of them.
In fact if it wasn't for me catching him 'in the act' on camera every now and then, I would wonder if he was actually breeding the gals as there is no squawking or carrying-on at all, it's all very hush-hush, and he isn't just doing a jump on and savage the poor hens, he actually takes his time and the hens seem content to let him do his thing...
It's a huge relief for me, as my poor Silkies esp. where getting roughed up so much.
Once Autumn come you will see a huge change in him, and he will be older next Spring and I am sure you will have no issues at all.
