Pft! You don't have to separate them at 8 weeks!
Fighting is a natural process. It lets them figure out how the pecking order is going to work and who fits where. Without a pecking order, the birds are stressed. Once they get their order, they will calm down.
When you notice the combs getting very red and the wattles beginning to drop down on the males (while the females remain pale), you may notice some changes. Generally speaking, the males won't attempt breeding until around 4 months of age. Mine usually don't start until well after 5 months, but each strain and breed is different.
