Hi,really sorry to read that your two are fighting, I guess from that the male is coming out of his nest box now.
The photos of mine in pairs are the rare ones, very few of mine will happily sit side by side. But I like the photos of when they're together, so I tend to upload more of those. I make a distinction between just squabbling and fighting. Most of mine squabble all the time, even siblings that have lived together since birth. Fighting is a different matter, and can be so bad it can be fatal. Luckily it's never happened to me, but I have had to step in on some serious fights. So some of mine have a few nicks in their ears where they have got in to a scrap. Your problem might blow over, as I've noticed that the females can be a bit tetchy this time of year. The males do get more placid as they grow up, but the females throw their weight around more. My female Toto lives with his brother Acorn, and lately she has been chasing him away. But because they still choose to sleep in the same box, and she is out of the aviary most of the day, I'll keep them together for now.
One last thing that I find helps if you only have one aviary, is to put in flexible tunnels and/or tubes. If the one being chased has plenty of places to hide the chase can stop quickly. They seem not to bother chasing each other if they can't see one another. I also found that putting two lots of food in different parts of the aviary helps relive tension. They are just like kids, if one thinks the other has a better more juicy slice of grape, trouble can ensue.
