Mine also don't like millet. They both love to chew on paper though. Maybe you can start by rolling up paper or crumbling it like a toy and putting treats inside the paper & handing it to them once they get used to you being around them a lot and they are feeling better (healthier). With her weight being so low and the condition of the feathers being so poor, I imagine this is not the best time to try and actively bond with them since they likely feel pretty bad. Maybe more passive behavior, like just being around them in the same room and talking to them without the added pressure of touching or closeness.
@iamwhoiam No, but it's not because of a lack of trying on Gizmo's part in the beginning. They get along well most of the time and frequently sit together and preen, but Darby only preens Gizmo for a few seconds as a way to prompt him to preen her or regurgitate for her and she never regurgitates for him. She doesn't care that it should go both ways. She really has no interest in returning the favor for Gizmo except as a ploy to get him to continue preening her. He doesn't mind for the first hour or so, but after that, he'll ask her to stop and when she doesn't, he'll fly back to his cage or somewhere next to me as a detour away from her and occasionally she throws a fit when he does that and flies after him like she's going to force the issue and I have to sternly say her name so she leaves him alone because it intimidates Gizmo.
However he doesn't like taking his meds and he is getting tired of me poking a syringe in his mouth twice a day so he lashes out. He bit me through the towel. My other boys will bite, too, though and it isn't always predictable.
