My old budgie is named Ghost and my new pet store bought is named Taru.
Ghost refuses to bathe no matter what I do. He only drinks from baths and won't get in. I've tried getting him in with millet, his favorite toy and putting greens in the bath. I've also tried a variety of bathing dishes in size and shape and tried with running water. He just won't. He has stopped biting as much though, but still loves getting scratched around his head.
He was very happy with me and his toys but he acted weird one night, his legs were stiff and he was all puffed up.
I was scared he was depressed because I read budgies can die from it and I got really worried. So I bought him a friend.
I am honestly running out of patience. I have done everything you said, put them in different rooms, play music and have short interactions with them several times a day. Ghost is playing and singing constantly while Taru is only calling for Ghost. It's been going on for three weeks now with no change. He screams the same note over and over as loud as he can while he tries to push his own body out of the cage. All day every day. He doesn't show any natural budgie behaviour to me. He sits completely frozen while I'm near, and looks almost psychotic trying to get out of the cage when I'm not.
I thought the screaming would get better if I just stayed patient, but it seems to me now that the fact that they can hear each other might be stopping Taru from settling in at all. He does eat and drink though but not if I'm in the room. I don't have a big apartment. Only two small rooms plus bathroom, so I can't separate them further.
I only said Ghost had turned evil as a joke. He is the sweetest budgie I've ever met, and I worked at a pet store for years. I was surprised someone so gentle could bite so hard. I just wanted to know how to get him to stop. And when I said how to discipline, I meant how. I knew it was with positive reinforcement, but how do you use it? I didn't mean punish if that's what you thought. I read that you can remove a positive stimulant for a short amount of time, like your hand when it's biting, to discipline it. Is that possible? Or should I constantly reward it when it's not biting? How does that work?
Am I doing things right? Is it ok that I've seen no progress in Taru in 3 weeks? Ghost has calmed down with his aggression towards me and is much better. I just don't know what to do with Taru. I almost regret getting him at a pet store since I know how traumatised they get there. I didn't think it would be this bad. He is a baby who should be playing and exploring
Not being shut in a cage all alone when he hates it so much.. I feel horrible for keeping him here.. His feet look red and irritated from fighting the cage so much. It's just sad.
It's actually been over 5 weeks since I separated them.
