My jenday's behavior

I recently bought a Jenday conure a few days ago. I do not know if it is a male or female. He doesn't like when I put my hand in the cage so I can get him out and play with him.

When he does come out, he then usually gets on my hand and climbs up my arm to stay on my shoulder. If I start stroking him, he fluffs up his feathers, pulls up his head, and makes this weird clicking/chirping noise. Is this mating behavior?

I also am not sure if he was socialized properly because he really doesn't like when my mom gets anywhere near him.
