Yep he's a Cornish Rock rooster (meatbreed), and even if you could have roos, he would get too large and would likely injure your hens, that breed was born to die, so it would be best to butcher him when he reaches a good weight or he may grow too large and start having leg problems.
I agree he looks like a Cornish Rock. I had a dyed Easter chicken from a local feed store back around 1997 that was what I believe a Cornish Rock (or similar). He was on a feed schedule and only feed so much a day, so he lasted about 5-6 years before he lost his legs. They just collapsed with in a week. You can't keep another rooster you could slaughter, sell, or give him away. Anyway you go best of luck.
Oh my.............................
Please someone take him away before I get to attached......................
I could never um,um...do the deed to him!!!!
