The other time could have been while she was in the aviary with Truman. I leave the two of them in there all day long and lately it seemed like they were getting along better. Yesterday the aggression began and I found some dry blood on Truman's toe but no substantial harm. I didn't notice any fighting today but you never know. It's possible that she was asking for it and bothering Truman and he did that.
The hole is pretty big (especially compared to her size). Also it's not clear in the picture but a bit of beak is dented inward in that area from the same impact.



So the main reason I am posting is to find out how bad this is, does this heel normally, and has anyone had parrots get injured from fighting and recover? I didn't spot any bleeding and Kili seemed to be pretty normal so I did not rush her to a vet when I discovered this.
Another thing I'm curious about is for people with parrots who don't get along. How often do you find minor injuries on them? Is it a reality that they are going to get hurt like this from time to time or is it happening disproportionately too much with mine? Thanks.
