I don't remember where I read it but in the wild male BPs eat 60-70% birds and only 30-40% rodents and females are the exact opposite. So it ought to be fine but he might get hooked on them and if you ever sell him or give him away that could be an issue for the new owner and I hear it makes the poody wet and stinky. I'll try to find where I saw that thing about their natural diets
