I have three male budgies (all gotten at different times). Two of them have bonded, and they groom and feed each other all day long, but the third one is like an outsider. He is smaller than the other two, and the biggest bird seems to always chase him around, trying to peck at him.
Well, the other morning when I uncovered the cage, the small one looked like he had been in a fight!! His head and face looked funny... feathers looked wet and had some kind of faint brown spots on it (blood???) and he was not acting like his usual speedy self. I also witnessed the big bird go over to him and start pecking at him, and he seemed to not be able to move away as fast as he normally would.
I took him out of the cage and put him into a small cage by himself. I guess this traumatized him a little, because at first he was really, really quiet and didn't move from the spot he was in for hours!! Not even to eat. I coaxed him with some millet spray and he ate it, then went and got some water and after that he seemed to perk up and started chirping and stuff. He seems fine now, except that he's in new surroundings and seems unsure of that.
I put the cage next to the other one and they are chirping at each other, and the other two seem quite perturbed that he is not with them, and I guess he is too (???).
My question is, should I keep them separated forever?? Will he be too lonely by himself?? He has his favorite mirror in the cage with him and seems to be having fun trying to "feed" it.2 (He never engaged in any feeding or grooming activities with the other two birds though!!
