Hello Qtmomo112 and welcome to our family, so glad you could join us.
Congrats on adopting an older bird, is this your first grey or first parrot?
You will find loads of useful information in the threads here so be sure to read them thoroughly and do ask questions you may have and we will help you in any way we can.
One thing to stress is allow this grey to settle into his/her new home and get comfortable, don't push for more than he/she is willing to give and let the bonding process begin, it takes time to build trust as it must be earned so let him/her set the pace and enjoy your grey.
Pictures would be most welcome.
