I know this is going to sound terrible, but I really don't.
I live alone .. so they don't get exposure to another person in the house.
Of course, I've had company over and such .. but most people only want to look at the birds from a distance.
My Cakes are the friendliest .. they'll go to anyone, esp. small kids, for some odd reason, they like kids.
Jazz will go to just about anyone as well.
Squirt goes to anyone, but to attack, he does not like strangers.
The rest pretty much shy away.
I never really had an opportunity to get them more socialized with people .. I truly feel strange saying "hey, want to come over and play with my birds so they get used to people?".
They're not like dogs, where you can bring them easily into a public place and let people pet and touch.
So .. I guess I don't really have anything to share .. I'm a bad, bad birdie socialization momma.
