red canaries

I bought a pair of red factor canaries, but he only sings the outside. Why might this be?

Volume (men and women) out of my yard and sings, but when you're inside, which is most of the time, does not sing. What should I do? I would love to hear your song inside my house. No red factor canaries sing like an American singer canaries?

Maybe your canary to sing when Heres encourages wild birds in your garden? My bird is the same way. I like talking to the birds outside, I guess: p
