It may be their way of establishing/reinforcing the so called pecking order. One will be dominant and in charge. The other needs to be reminded. :-) If they're not causing injury to each other, I'd say let them be together and sort out their own squabbles.
Your right, good advice like usual. How is yours doing? My girls are still timid but I get them out of the cage at least once a week, they don't want to leave the cage for some reason.
You wouldn't believe what I have right now. No birds at home but I am raising 2 baby skunks. One was brought home by someone's dog. She was trying to feed the baby (only a couple days old) and let her dog do the potty part, licking the skunk. Not a good idea. We talked her into bringing the baby in.
Since it was so young I was asked to do home care for it. A single mammal baby is bad news. But be careful what you wish for. A week later an orphaned baby skunk about the same age was found by its dead mom. Now I have a couple of stinky fuzz balls.
Yes, they can spray but won't if they're not upset or startled. So I'm being very careful. :-)
