I have to say that I was shocked to read that someone was considering having a healthy bird euthanized. I can't imagine any circumstance except a painful, terminal illness where I would consider this option for any living, sentient being. I've given some thought to where Timber would go when my husband and I "pass." All of my boys have expressed an interest in taking Timber, and I would trust any of them to do their very best for him. Greywings also pointed out some excellent options.
Since I am a rehomer, I know that adjustments are slow and often not easy. I'd like to think that many like myself and others on the forum do their very best to give their birds a loving, healthy home. I'd also like to think there are more of us in the world than the kind who see birds as a novelty. While it's a slow process, birds, like humans, can learn to love again and form a bond with their new caretaker. I am very pro-life when it comes to animals and people. I'd hate to think that the chance of a happy life would be taken away because of the fear of a bad life.
Just my thoughts..
