Hi all.
I have a dilemma...A client is offering to GIVE

me a B&G (Mango 4 years old) with his cage, all his accessories and food for FREE. They really don't want to give him away, but when dad leaves the bird starts screaming and won't stop. Mango is very attached to dad and quites down when he comes home.
I have 4 dilemmas: 1) is the only place I have to put the cage is in my foyer (a small room actually with the front door across from the wall where the cage would go) 2) Mango's screaming and 3) I have an M2 and am worried about Ki learning the behavior. He is a very well behaved M2 and I don't want that to change.
4) I also know that M2 dust can damage Mango's lungs...can a HEPA filter eliviate that?
UPDATE: Mango was apparently reacting to the chaos in the house (3 year old neice coming to live, grandma visiting, etc ), has stopped the screaming and has become "normal

" again. They are willing to keep him until August (I have to do some repairs, the main being the a/c ducts need replacing).
So, can I have opinions on the possiblity of Mango learning to live in a new home and NOT corrupting my M2 and on the placement of the cage. Actually any and all opinions and comments would be appreciated!
Thanks!
