Worried!

Hi all
I have 3 Boa's & 1 corn which a lodger left behind{All not kept properly, no adequate heating ect!}. Having heard nothing from owner I decided to keep them.
1 Boa a male about 2yrs old but very small{smaller than the 10month old salmon Boa.} I was handling him regularly & he was lovely. He hadn't eaten for the 3months the boy had him. Now it's 5months & still he won't eat! Tried fluffs, medium mice & small mice regularly, tried moving them about like a live rodent would, but he turns the other way as if he is scared of them!
They all had mites, which have been treated now.
But this one Boa was in with an 11month old female & the 10month old male.
Last week he started being very offensive to me. Then two days later I found young male, alone & shoved out of the hide. I removed him from viv' as he was so very traumatised!
Next day the female was snuggled up to the still nasty male. But the day after I found her evicted & very nervy so to help the situation{which I believe to be 2yr old male being offensive to her}
I removed him from viv'.
He flies at the sides of the tub he is in now{tempoarily}whenever anyone passes it!
I am so worried about him. My son who keeps snakes went to check him out & got tagged rather deeply, drawing blood.

Does anyone have any idea's why he would have turned so nasty even to his own kind for apparently no reason??
This boy has apparently been neglected before the lodger had him, so i'd love to be able to make him a happy Boa & show him how his life should be. He deserves it & i'm worried that I might lose him.

All the others are making progress eating, growing & shedding well. All very friendly & love being out & handled now.
