I took this from another forum from a guy who is just amazing with his birds and his training ... please follow these directions and you will have no problems what so ever.
"Disfavored Person Behavior Mods.
Put a training perch in a neutral room (a room that your bird is not or less familiar with)
Using the “step up” command have the preferred person take the bird from its cage and to the training perch
After the preferred person leaves that area (out of sight and no voice heard), have the less preferred person enter the area and sit and talk to the bird calmly
Be animated and expressive and use the bird’s name often.
Using the command “step up” in an assertive fashion, have the bird step up onto your hand
If successful, praise and compliment
If not successful, scowl and give a brief disapproving look and say it again and insist on the step up
Repeat for a minimum of ten minutes (make it as fun as possible, keep the energy level low if stressed)
End with a calm conversation using the bird’s name and lots of praise. At the end of the session, the favored person comes in and returns the bird to its cage and rewards it.
If the bird is not at all tame with the disfavored person, then do the basic taming and training exercises described in the birdbites protocol. Twice a day for two weeks should see marked improvement for most disfavored person behavior troubles."
