Proven Pair Red Bellys

They are proven for previous. Both are closed banded. I was told they were 7 when I got them and have had them 3 years so are 10 years now. Both in perfect feather. Two of the three years I have had them they were with my loud conures and didn't have a nestbox. The past year they have had a nestbox and were moved to my grey room but haven't produced for me. They were surgically sexed by Dr Scott this past fall and are both viable and ready to breed. I'm moving so selling a few pairs before I move. Can ship. $500 for the pair. Located in Ann Arbor MI
