Makes sense :emoticon112:, I thought it had it to do with other budgies in the aviary which the parents would find hard to cope with but anyway, I will find a good sized kindy cage. I wont be doing any breeding until my outdoor shed is built, I'm still researching the prices and what sort of shed I will need so if people have some ideas about outdoor sheds that would be great. I plan on putting my cockatiel cage in the shed along with the budgie aviary I'm getting, their will be one breeding cage, one nursery cage and one kindy cage. Since I'm only breeding one pair just to start of with I'm not going to make a big aviary, though if things are successfully in my first attempt at breeding, in the future I am thinking of building a small section in the shed to rest the parents, instead of using an aviary cage I would build a suspended aviary which I have access to from inside the shed, I would use my aviary cage for breeding cockatiels in future and I would probably use the kindy cage for resting cockatiel parents if I do breed them. But thats in the future if things go to plan, for now I'm only breeding one pair and I will see how I go.
