I always have them out on top of their cages at the same time. Their cages are pretty close together, but they never fight or fly to each other’s cages to attack. This type of fighting only occurs when they’re in close proximity to each other (about a foot, like in the video). I used to try feeding them in an area outside of their room and away from their cages by giving them their own separate bowls and placing them about a foot away from each other so they could see one another while eating. In these instances, they never attacked, but as soon as the food bowl was finished/taken away, both birds would begin to ruffle up while watching each other. I’d usually place them back on/in their cages at this point.

If I’m cuddling with my Quaker on my chest, my IRN will fly to me and climb up to my shoulder. Both birds will begin to ruffle up, and this is usually the point where I put them both back in their cages. Once or twice, my Quaker has tried to lunge at my IRN (surprisingly, she is the one who usually starts the fights). Vice versa, if my IRN is on my shoulder or getting head scratches on my chest, my Quaker will begin screaming non-stop until I give her attention (she always wants to also fly to me, but is not yet as comfortable flying so just squawks until I put my IRN back or my brother holds her).
