I hope to have my outside aviary built by the end of the year. By then all the ringie gang will be over a year old. What I am thinking about doing is if Pepper is a girl and Ollie is a girl buying two cock birds and letting them pair up and have babies (will have a divider down the center, so two separate flights). Both Pepper and Ollie were hand raised babes, but neither are what you could call 'clingy' like Silk and Biscuit. They will tolerate a pet now and then but like to be left to do their own thing which is more then fine.
What I would like to know is it cruel/mean/horrible to move them outside and breed with them? Am I a bad mummy to be entertaining the idea?
Opinions needed please?
The weather and protection for predators is not a problem or a real worry, I guess what I really want to know is will they suffer from going from a 'companion' to a 'breeder' bird?

I have no idea whether they'd suffer going from companion to breeder. I suspect that depends on the individual bird. May I, however, make one comment? I don't know about the rarity, desirability, or high-maintenance factor of ringnecks, but in much of the pet bird trade nowadays, there seems to be a surplus of everything, and I suspect that within a generation the surplus will be as bad as the cat and dog surplus. Are you sure that you're ready to deal with the implications? I mean, someday, one of your beloved babies might end up unwanted, and like some birds are already having happen to them in larger shelters or places not set up to take care of them or send them to places that can, it might end up being euthanized simply because there are so many unwanted pets out there. As someone who once had the unpleasant job of "euthanasia technician", the thought is abhorrent to me.

That might be just one factor to consider when you decide whether or not to breed your birds.

That is a good point, and something that I admit to not having thought about. As much as I may want to I could never keep all the babies that they would have. Like I said its somthing that I am thinking about at this stage.
