so i bought my Indian ringneck about 5 days ago, in the shop the owner told me that he was very friendly and doesn't bite yet he failed to show that, i bought the little guy and i trained to step up the first day and all was good, but then the second day is when my trouble started, he would want to go and sit at the window and i would pick him up and take him there and back, but when i want him to simply step up he wouldn't anymore he eats from my hand but when i try to pet him he would bite, and when i move close to him he would move away, plus i saw him shiver a few times, i really like the guy and i dont want to give him back so please, if have any ideas on how to train this guy or fix these issues tell me i'm begging
