hello everybody. i just recently got 2 congo african greys. one male. one female. aprox 11yrs old 5 days ago. i have had some issues with one being aggressive towards me. when i go into the cage at all the male like you would expect would just kinda move away when i go to change food, water, etc. the female who i was told was the sweetheart of the to of them doesnt show many signs of being aggressive like growling or puffing her feathers but will casually climb to wherever my hands are at just to try and bite me. the male i also just noticed this morning has been started feather plucking under on of his wings. im planning on making an appt with thee vet tomorrow to get all the check up and everything done but as a first time bird owner it is a little nerve wracking. any advise helps.
