Mixed Aviaries

[JoeS76]

Hi All, I'm new to finches and was wondering if I can put Yellow siskins with my Green Singers in the same aviary? Aviary size is 4m x 2m.

my personal view is NO. on the basis that they may cross breed and are from the same Fringillidae Family.
if you want pure breds - avoid this. live food is important. as well as niger, and maw seed....live feed could be meal worms , maggots or termites
