Aggressive Green Cheek please help
A few months ago we rescued a green cheek conure which had been brought into a local vet and not claimed for more than 2 weeks. When we first got him (unsure of sex) he was cuddly, after a few days he became nippy as he always wanted to be with someone.
He then began to chew his own tail feathers. His tail feathers are about 1 inch long now as he always chews them. He has been trained at some point as he says 'What are you doing' and 'Stop it'. He also spins around for a treat. He will come out of his cage and has accepted the house routine for birds, Breakfast, sleep, play time and so on.
He has started biting to the point of no return it is out of aggression and out of nowhere at times. He will be happily sitting on your shoulder and then he will bein to hiss and demonstrate aggresive behaviour, he is drawing blood, this all has the potential to alienate him from the rest of the family which is not what we want.
As we did not know his upbringing we decided to take on another rescue this time a 6 month old green cheek who was not hand tame. They seemed to get on really well, Leo(Older and more Aggressive bird) seemed to take on the care straight away, feeding him and cudling into him (again not sure of sex). They both play in the same cage during the day, and on the same Gym, however they sleep in different cages. We did attempt them to sleep in the same cage however the baby seemed to be being bitten. The older conure will not attack the other bird at times and Hiss to the point that the baby conure is now begining to display those behaviours.
I love my birds and would like to be able to keep them all however I am affraid that either a member of my family or one of the birds will get injured.
We have a 1yr old Alexandrine however have never allowed them to play together due to the size difference, they live happily in seperate spaces of the same room.
Please help, every site i see says GC conures are happy birds, it seems as though this conure may have been ill treated, does anyone have any tips on how I can help this bird - Do i need to go back to basics, seperate cages, sperate rooms etc. Please help any advice is appreciated.
