Hi,
I have had my AG for 15 years now, and I've always boarded her going away on vacations. Only a small number of times i took her with me and only twice she flew with me. I have no one to trust to come in and watch my birds. What's great about boarding them with an avian vet is they get attention and they get to be around other birds for that time, and who knows what new noises they pick up. My DYH magna picked up "open the door". Leaving them at home, means no one is around except the time someone comes in to tend to them, that means no human contact. If you have to do that I suggest timers for some lights and a radio, and just set it to come on at a certin time and turn off before they fall asleep. Hope that helps a little.
