Anyone out there have a silkie roo who is overprotective of the silkie chicks?

I have a silkie cockerel named Blackie who is 6 months old, the sole surviver of a poor hatching. I also had penedescena chicks all of which turned out to be roos. I kept my pennie roos and Blackie separate. Then when a more recent brood of silkies were ready for the great outdoors,I let them share a coop and run with Blackie, although I was afraid he would be jealous. Up till then, he walked with me in the yard everyday and wanted to be picked up and hand fed. He was aggressive with the chicks for a couple of hours, and since then,he has decided he is their guardian. He runs across the coop and attacks my hands when I go near the chicks.. Now I have to pour the food into the feeder from above. To refill the waterer, l have to trick him. He displays all of the aggression of the most obnoxious rooster even hatched but protects the six little ones and never is the least bit aggressive with them.But they are getting bigger. I hatched them from fertile eggs and silkies are hard to sex. They are now three and a half months old. I suspect the worst is yet to come if any of them are roos,and with my luck, most of them will be. I would really have a hard time culling Blackie since he was once my sweetheart. Any hope he will grow out of it? On my parcel I can have 2 roos, my Penesdesenca Henry, and (I thought) Blackie would be the second. But I am an old henwith tissue paper skin and my hands and ankles look like a punch card. If I grab him with a bathtowel and restrain him till he calms down, he lets me pet him. If I put him down, he will walk like we used to--Sometimes. Other times he just flaps his wings and makes a run at my toes.
