Avalon thankfully put me on a waiting list and said it will be a few months but it will be worth it.Rita Garris of Rainbow Parrots used to breed Meyer's parrots up until last fall. Due to personal reasons, she placed her breeding pairs with another breeder. You may be able to contact her for more information as to who else breeds Meyer's parrots and other poicephalus parrots.
