Sudden Aggression in Male Ekkie

Ok so about a month ago my male eclectus has started exhibiting aggression towards my mother. I do not live in the house, however plan to take him when I no longer live in an apartment (mine doesn't allow birds). Because Ive had him so long, he is very bonded to me. It started with food aggression and moved to random bites not associated with any specific activity or place. It has gotten progressively worse and he is about 13 years old, never ever had aggression problems before and we've owned him since he was 6. He still won't show aggression towards me, but I'm not there a whole lot right now. I was wondering is it diet, hormones, or god knows what? He eats a lot of cooked food and gets roudybush brand pellets (suggested to me by an Ekkie breeder). He is not locked up during the day, he has a bird safe room and TV to himself. I am just hoping we can do something to bring him out of this or if it's hormones if there's anything we should or shouldn't be doing for him. Does anyone have any advice? I have been thinking about flower essences to help calm him, any thoughts? Any and all advice greatly appreciated!

Hi, if this behavior is out of character for your bird & he normally gets on fine with your Mother I suggest a visit to the Vet for a complete check up. It is most likely he isn't well or is in pain.

He might be going a little stir crazy even with having his own room and TV.

Maybe you should let him have full run of the house.

Let us know how that works out.
