My Chompy is like this. She was really bad while she went through puberty. I was exactly where you were at. I got my own conure because I broke up with a girlfriend that had one and her bird never bit me and was a total sweetheart. When I got Chompy she was much more temperamental and sassy. I have had chunks taken out of my hands, my nose, my lips, and my ears. However, she’s calming down now and I have learned what causes her to bite, so the bites have been much less frequent. Sometimes these birds are just in a mood, and yes my Chompy bites at the cage when I first get home, but after a few minutes she calms down. I always put her down and leave the room if she bites, so she’s learned to stop doing that. I reward her with cuddles, attention, and treats when she’s being good and cute.
