Hello, my male budgie has been developing aggression towards me. He started biting me whenever my finger approached him in his cage.
He used to enjoy my finger tickling his cheek and rubbing his back but now not at all and he would fend off by biting my finger. He has been showing this aggression since early this week and I wonder why.
I got him in late Oct 18 and the store told me he was about 3 to 4 months old. So he should be at 9 to 10 months old now. Could he be in some hormone change?
He has been fed well with seeds, apple, broccoli, spinach and spring mix vege.
Thank you! Would you know how long this would take? He usually allowed me to send him to bed every night and let me pet him whenever I turned off the light for bed time. Last night it didn't seem so, not only he would bite me but also refuse go to bed, continue playing with his toys despite I covered his cage with blanket.
