I just thought I'd share this as it seems to be very effective with Alfi - she knows exactly what it means.
When Alfi is doing something she shouldn't be, like chewing the couch or pinching pens I give her three chances to stop and if she doesn't she goes into her cage for a wee timeout. The first time, I remove her from say the desk (with a verbal warning) and put her back on her perch, the second time, I remove her (again with a verbal warning) and take her on an open hand, towards her cage - obviously she flies off and usually goes straight back to her perch. On the third offence I take hold of her and put her in her cage. I don't often get to the length of the cage now with her, so she's def getting the message - it seems to be quite effective.
Hope you and yours are all well.
Lyn & Alfi
