So I have a few concerns here. My

does not want to go back into his cage when it's time. I have tried everything from buying new toys, rearranging his cage, and giving him treats but nothing is working. At first giving him treats worked until he figured out a way to eat his treat while still on my finger instead of stepping down so when he's done with his treat he bits me because he doesn't want to go inside. It's getting to the point where if I even bring him close to the cage he starts to bite me.
The second issue is that my parrot seems to hate my boyfriend. What used to be a great playful relationship has went out the door. Every time he gets close to our

he tries to bite him. This just started happening a few weeks ago when we tried clipping his nails( epic fail lol) since then on every time my boyfriend seven gets close to the cage our

goes to bite him. It really makes me sad because it wasn't this way at all before, he would play with us both. My

is only 6 months old but seems so aggressive with him! Help me guys and gals please!
