Ok so at the pet shop I work at there is a 30 year old B&G macaw named max he is a rescue and he was physically abused before he came to us. Max has been at the store for about 10 years and in the whole time he has been here he hasn't bonded with a single person or other bird and he hasn't allowed anyone to put new toys in his cage because if you open his cage he will attack you. Is there anything that I can do to help this poor macaw or any way to make him a little more content with his life.
Twenty years and likely a large number of homes(?) and pet stores and the last 10 years, likely center in this pet store. Add physically abused and should anyone be surprised there is no trust of Humans.
Get him off the Pet Store floor in back in an area that is more relaxed and comfortable.
Limit his contact down to just a few individuals that can be trusted 'alone' with this or any Parrot. Pet Shop staff have just as many idiots as the general population. Pet Shop Staff that abuse store pets is far more common than one would believe.
After about a week, serious one is one would be the next step.
Lets face a reality here, any Pet Shop Owner cannot afford to commit 'paid staff' to a single Parrot for the time that is required.
It is an interesting reality that most Pet Shop Staff are working to pay for the Parrot(s), etc... that they have purchased! Take care you don't end-up with more than you can afford in either time or money!
