2 months ago my male zebra finches male companion died. I had been hoping to give him a new companion to help him enjoy the rest of his life, however he is really quite weak and has an old leg injury which I think would make him too vulnerable to being introduced to another bird.
At the moment all of his perches are as low in his cage as they can be but he still struggles to get onto them and often falls down. The bottom of the cage is lined with lots of kitchen towel to cushion him when he falls. Although I still offer him out of cage time by leaving his cage door open but as he can no longer properly fly he only over pops out and then pops back in. He saw a vet about 3 months ago who said that he is healthy enough but that he is old and frail. He has since been on a calcium supplement and had a course of antibiotics but I can't say he has improved, aside from gaining a gram and a half.
He still sings daily, but I'm obviously worried about him

Thanks in advance for any help everyone, it's great to be a part of such an excellent community. Thanks so much.
Alison.
