Great story and congrats on your new baby.
Yes, broken tail feathers are very commons for baby birds, they fall a lot, it always amazes me how they survive in the wild. i guess they don't fall from trees much.
Macaws form very strong bonds with their owners so I'm sure you will have a great relationship with Jax.
Do your homework on making him a bird room and remember that birds are very social and love to be around it's owner much part of the day.
Macaws are not too expensive so I hope you do not face money issues. The most expensive thing when it comes to Macaws is Cage, playstands or gyms,toys, some foods, vet visits. I approx spend $1700.00 year for both my boys not including cages and playstands.
I'm not sure if you have taken a shower with your Macaw so if you have not, I would advise you to do so ASAP, they just love showers and this speeds up the bonding time for both you and your Macaw. Love the picture of Jax and best of luck to both of you. Joe
Not all macaws like water. Mine is terrified of it from the day he came home.
