i have a 4month old sun conure, male. All he seems to do is nip my neck. he would bite my hand but with no real force when trying to pick him up but now the biting seems to be getting harder. i've tried blowing in the face, doesnt work, saying a firm "NO BITE", doesnt work. i've searched online, and i came across using a Popsicle stick to put in his mouth every time he nips me. it hasn't really been working, seems like the biting is getting harder. can somebody please give me some tips on how to make him stop biting. other than him doing this he is the most affectionate bird i've ever had. its just frustrating when i'm trying to hold him and all he wants to do is bite. someone please help. i'd greatly appreciate it!!
