Being a former bird breeder it isn't easy to find a pair that will mate... that is even eager to accept the male or female of our choice.... and if one or the other isn't receptive the damage that can happen can go as far as death to the unresponsive bird....
It would be wonderful if they could copulate and then remove one or the other...you can't as it takes two parents to sit on eggs, to do the husbandrt duties, that is feed and carry to the nester...
Unfortunately seldom do they make ideal parents first time around and you will be left hand raising the chicks... that's if they would even allow you near them and the aggression to the human can be severe, to the chicks devastating and you then in all probability loose the "tame" bird quality.
Instead of going into the needs of newborn chicks and the dollars associated with setting up a "nursery" it would be wiser to consider if breeding is the forte, to either of you buy out the other (bird) and then house them together in the same room, not same cage, for as long as it takes to see if they will be receptive... or if money doesn't change hands then the other who relinquishes the bird gets first choice of the brood...
I have know breeders who have introduced two birds into a nesting situation, the hen normally will go to the bottom of the cage, be harrassed and stressed that should mating occur there is no fertile egg, and she usually will wane and remain terrified... so unfair but those breeders cared nothing for their birds, but it was the dang dollar that spurned them on... In the long run they lost all the way around...
This is with the larger birds, not the overproducers, but those birds that their system is so geared to definate "seasons."
