We feed our RB2s a mixture of Zupreem fruit pellets and ABBA seed mixture (no they do not speak Swedish yet). They also love fresh and cooked veggies and other little goodies.
Both birds are in the normal weight range now. Hannah who was overweight is in the higher range of normal, and Harry in the lower range of normal. One thing that really helped Hannah was exercise. We quit clipping their wings and they are exercised twice a day and fly from point A to point B in a game type fashion supervised. Hannah hated it at first and could barely fly, now she cannot wait. Harry is a little air force bird and can do all kinds of things. Hannah now is much more active and Harry is less stressed with this exercise.See my former post:
Of our two RB2s, Hannah was too heavy so she was restricted to pellets with just fewer ABBA seed mixture 70/30. Harry was too thin, so our Avian vets had him on ABBA seed mixture/pellets 50/50. He has gained weight as he has got older. We also removed stress situations which helped. ABBA seed is the only kind our Avian Vets recommend.http://www.abbaseed.com/
