Breeding cage for an Amazon Gray Parrot
The size of the cage required for breeding Amazon Gray Parrots should at least be 2 feet wide, 3 feet high and 6 feet deep. You should try to make the cage look natural forest because that will keep them comfortable.
Keep the cages in an L shape and keep the entrance and exit from the top. In wild parrots build L shaped nests and have the exit and and entrance to the cage from top. Try keeping wood chips, coconut fibers but in small pieces, dry grass or hay should be kept at the bottom of the cage. Keep these things so that the parrot can comfortably nest.
