The cage is 34 high 31 wide 20 deep. They main object of bickering is a grapevine perch at the top of the cage. They both like sitting next to the bars. I don't know of its due to being closest to the window or if its the iodine block.
I did some rearranging of perches, added a couple more and took one out. Also added in another iodine block.
I'll try to get a video but it might be hard, they usually stop if I stand up or get close to the cage.
Here is a short clip of the sounds. Angel is telling chiffon off and you can see chiff move away from angel.
