All parrot species are different, so this section of the Omlet parrot guide can only cover the basics. Specialist advice should be sought for the species of parrot you want to breed.
Breeding parrots need to be separated from other pairs, or from a non-breeding flock. Birds with eggs or young are very territorial, and fights are inevitable if other birds are around. If you have more than one pair of parrots, you will need a custom-made breeding aviary, with separate sections for each pair.

How Much Space Does a Breeding Pair of Parrots Need?
Medium-sized parrot pairs (e.g. Cockatiels) will need an aviary space at least 140" long, 35" deep, and 70" high. Within this there needs to be an indoor space of at least 45" and 35" wide, containing a nesting area. Raising this covered section from the floor and lining its base with wire mesh makes a breeding aviary easier to clean, as most of the droppings will fall to the floor (which can be concreted or tiled).
Flock birds such as Cockatiels, Budgies and Lovebirds can cope with confined breeding spaces better than more territorial birds. Non-flocking species will need a lot more space, to enable the male and female birds to have their own personal space.
