I'm just not finding info on the compatibility of the grey singer, so that's the one I question the most. Currently he's in a divided breeder with the firefinches. They can see each other and their food cups are on the divider, and they don't even seem to notice one another. But before I put them in the cage together, I want to be sure I'm not asking for trouble.
(And yes, if I get some gouldians or new birds, I will quarantine before adding them to the bird room).
