1 mated pair of parakeets and a single yellow female with separate cage. I would prefer that the go to the same home as they have been together their entire lives and are now 5 years old. The yellow female is a plucker and needs a home with a lot of natural light. I have tried the specialty lights for her but she does much much better in the sunshine. I put her outside in the summer and her feathers regrow. I keep a foraging bowl in her cage to help prevent the plucking as well.
