Some of same advice as I posted previously, along with: plenty of roosts in corners of run (2"x2"s at 24" above ground) and other locations for those that wish to retreat to do so (they usually don't back off but will get up on roosts to take a break). Keep a bottle of betadine handy to daub any open wounds. If you have a lot of flies and you notice them lighting on abrasions - a tiny bit of Adams tick & flea spray will keep them off. Our jakes never had wounds that became infected and they healed up pretty quickly (born to spar). Assuming yours have lots of room to rumble, just keep an eye out for any sustained ganging up on any particular bird (separate). You can also separate preemptively (at 5 weeks this should work well) separate out a different poult, every day (pref. the most aggressive). Crowding can result in more sustained and potentially damaging bouts. Also, at 5 weeks of age they can fly up to a roost to retreat. Ours started early and were pretty brutal. We applied the old school "remedy" pine tar to their head and necks - seemed to slow them down a bit as the taste is appalling, but that was at 10 weeks. Took awhile before a pecking order was achieved (three jakes in our first bunch). However, the loser took the worst "real" damage from the jennies (actually trying to remove divots of flesh from low guys on totem pole) and had to separate the females for a week (seemed to forget about their wanting to coup de grace the fella). Again, at 5 weeks, the sparring is more play than serious practice and is shouldn't be a dawn to dusk affair (give them a couple of months more). By three/four months they can often be absolutely intent on sparring and nothing else. The greatest potential for serious injury is their knocking over ladders/grills, etc.. Once they get their order established they will get along fine. Come breeding season, take precautions outlined in my previous post.
