Ever since she got her new cage on Saturday, Kaleeko has been awful! She bites when stepping up and then immediately flies to your shoulder and begins biting neck/ears, etc. Her bites have gotten hard too. Could it be from the new cage? I also read you aren't supposed to let them on yoru shoulder that often, and she has been on our shoulders a lot. So we started doing the step up over and over method. She doesn't bite when you do it, but she just gets bored of it and flies to the top of her cage where she begs for apples (she LOVES apples). She also does not want to get back into her cage. My son is getting frustrated and he's covered in bite marks. Any tips on breaking his nippy phase?
