Sure the pet store sold you another bird but they didn't tell you
they will bond to each other more than you i betcha. Did you have
their wings clipped? Thats first step.
I just put birds on my shoulder to cuddle as well as doing 'step ups'
now and then. My guys play independently in and on their cages or
if you have a mirror in the cage remove it. they will both bond to
that birdie in there.
keep offering fresh foods. not too much orange it is full of acid. I
only give apples once a week. Green leafy stuff is best for them.
