You're right it is the breed. Last summer I ordered pullets, and received a straight run instead. I had 6 roos, and they acted just like my pullets. Very active, ate about the same amount, the only diference was they were bigger and started crowing. We did order some cornish rocks last fall, and they were the most digusting things ever. They just lay around, ate, and pooped. They stank so badly!!! It was awful. I need to figure out what I'll do with my PP. I'm getting 2 silkie babies tomorrow, and I don't want them to get trampled. It maybe time to build a bigger brooder!! I was hoping I had a few more weeks.
