Hi Vicki5280 and welcome to the grey forums.
First you do not have to defend your choices as we all have had to make our own decisions when bringing our baby greys home.
My grey came home fully weaned and thats what we recommend for any person who has never hand fed a baby grey.
You said that you are a very experienced hand feeder so I don`t see a problem with you or your experienced friend finishing the job.
As far as the break away theory, I am not so sure that is all true when it comes to humans as many have finished the hand feeding and still have awesome greys.
Living life has its ups and downs and sometimes there is nothing you can do about it.
Phoenix will get over it and still love you. They know more than you think.
I have a CAG, a BFA and cockatiels that have traveled all over the country with us and they seam to enjoy the trips.
they are right with us and we talk to them all the time. they have even stayed in hotels, motels, friends and relatives homes and even camping.
Make them part of the fun when you travel and things should OK.
Chili may have your routine down and knows what`s going to happen. Changings things may help.
Cricket is in and out of her cage randomly all day long so going back is not a problem.
Hay Nilah, Cricket here. They never seam to learn how important we are do they.
Corky is always uncovered first and I think I should be number one after I am the good looking one IMHO.
When I`m out I never ever leave daddy because Corky will come over and take my spot and I will not let that happen. the left shoulder is mine and only mine.
Sorry about Whispers broken wing and a trip to the vet is the best thing to do and I hope every thing turns out OK.
I am so glad Whisper is coming home to you. she will remember you but it may just take some time for her to readjust.
Good luck with your home coming and the vet visit.
