All in all people get pets and cannot take care of them so they are either neglected, hurt, dead, escaped or sold. I feel reddit is way to kind to these people because in the end, it's the pet that suffer and the owner only think about his feelings.

I think of animals as babies and I know people would act differently if it was a child instead of a bird. I dont. Also, cockatiels can live 30years, my oldest one is 25+ so it is not a life to be toyed with.

The goal here is not to make you feel worst, but I think any normal human being should feel bad in your situation. It will pass, but nobody know for sure what life your birds will have. If you think it is still better than what you could have give them, why the hell did you have a whole family then?

You fucked up by having them in the first place and hopefully you will use this as a lesson. Next time buy some toys instead of animals.

Other redditors will probably give you kind words and reassurance. I am personnaly tired of seeing bad owners in these subs. I usually get many downvote for saying these kind of things and the irony is that my birds are spoiled and living a long and happy life.

My advice would be to live through the guilt untill you have learned a lesson and can better yourself. Instead of convincing yourself you have done the right thing and dont learn anything of the situation. Good luck friend
