If you post pictures, somebody can possibly sex them for you, depending on their age.
I agree with most of the other posts. Time will tell but odds are pretty good they will work out an accommodation and coexist. They will have to debate which one is dominant, but they will probably do that when they are quite young. The subject may come up again when they reach sexual maturity, but they can usually settle that without serious injury. If they are not raised together or are ever separated for a period of time, it does become more problematic.
Here is a link to a thread that discusses multiple roosters and potential problems. Good luck!
