I will be getting a Macaw soon, and I am completely confused between a Scarlet and a B&G.

I've done alot of research and both have their advantages.

I would really appreciate some inputs.

Also, I had options ranging from a 7 month old Macaw all the way to 3 years old. So my question is, what is the age that you won't recommend a bird to be bought at? When is a bird considered kind of an adult, and teaching becomes relatively tough?

Thanks
