This is Pudge ( the darker one) and Burt (on the viewers left) - this just started today!
Previously, Pudge would work his way over to Burt’s cage to pick a fight and I’d have to intervene in the squabble. Today, I was watching as they got closer to each other, and it looked like… Well, it almost looks like Burt is asking Pudge to preen him, as Burt has some pin feathers on the back of his neck that are still in the sheath. There was a minor squabble, but overall…
Are they bonding??
