Re: Worried about my baby flyer
one suggestion would be to have your sister visit you more frequently now, so Avion becomes more familiar with her while you're gone?
also, I don't know what her nest area is like, but the day you leave it couldn't hurt to tuck inside it either a tshirt/tank top you've worn the previous night/day, or else some other fleece, tissue or something that has your scent on it. this way, she still has "you" with her when you're gone.
7 days probably isn't a very long time, but the the absence won't go unnoticed by her. something with your scent on it will be reassuring, sort of a sign that you're coming back. I find that animals don't understand the concept of "vacation" and in their world, sudden unexpected absences from familiars usually signals something negative.
