I think the aviary would help yes, in small enclosures two males in the same enclosure is usually not a good idea, and 7 hens for two roos is too little. Separating them now might cause trouble putting them back together again though, but a bird with blood on its head should definitely be kept alone till it's fully healed. I wouldn't put it with a roo, you might not see him mating the hens but that doesn't necessarily mean he's not doing it - or wouldn't start doing it if the other roo wasn't there.
The roos can cause a lot of damage to each other and the hens by the time you get the aviary ready, so I would probably keep one roo alone, the fawn hen alone and the other roo with the rest of the hens (or alone). I wouldn't split the hens in two groups and give each roo a group, because 3 hens for a roo might be too little in a small enclosure. In aviaries it seems they do okay with larger numbers of roos per hen. They should all be able to see each other, preferably separated by a single layer of wire, to prevent fighting when introduced to the aviary.

One pair is doing really well. They have been in separated pairs since I got them a month ago.The first 3 weeks things were just fine, now the hen on one pair will not leave the male alone. I might give it a couple of days and see what develops. I have thought about an outside aviary but need to be carful of the homeowners association rules. Thanks for your comment.
The past 2 days the female button (light rear) has not been harassing the male. A couple of days ago I put them with the other pair of quail so I could clean the cage. Well they did not like this pair I added to their cage. Both male and female would not stop chasing the intruders. This must have been a good thing because when I took the intruders out and put them back in their own cage the female stopped chasing and pecking the male. So far so good. However, The light (cinnamon rear ?) female is extremely shy. Every time I approach the cage she runs and hides. I hope that over time it will get better. Dave
