One thing I was told by an avian specialist that is supposed to help with biting is to put them into a "time-out" cage, or turn your back on them. I was told that in the wild the other birds will turn their back to another that has offended them. I was also told if you got a "small" cage, like a carrier, that would be a good place to have a time-out. Just set them into it for no more than 5 minutes in a quiet, boring place in the house. I don't know if this a correct way of dealing with it though... maybe some of the other people on here have better ideas about it?? I feel for you though!! It's frustrating when you want to have a good relationship with your keet and biting is getting in the way!! Keep us posted!!
