I dont mean to be rude at all but i will be completely honest. she doesn't look that great. looks extremely dehydrated, not much muscle tone and what's up with her lower lip/jaw.
Need to get her/him/it to the vet and get it checked out. they need a yearly check up anyways and you should get it checked for parasites while you're at it
What is her set up?
what are her temps?
How old is she?
You need to leave her alone for at least a week and let her get acclimated beardies HATE change.
Again. I dont mean to be rude or anything. just looking out for the beardie
*Edit* sorry i posted this before i saw that there was a second page and that people had alrady adressed the need to be taken to the vet and the mouth situation. but still. whats the set up?
Oh and the being "calm" or "totally cool" when the other animals crowd around her/him is not because she ISN'T scared its because she IS scared, that's usually what bearded dragons do. they get scared and hold still in hopes that the threat will go away.
