Usually any animal will go off on its own if its not well, any weakness makes it vunerable to its 'friends'
Everything seems fine, just wants a bit of 'space' but I'd give her 24-48 hours, see how she is and if she isnt feeding, drinking, drop herinto the vets
I had a bantam like that, she was eating, drinking fine, just liked to be on her own, never took treats, but was always first when I was digging and had all the worms
Sorry I cant be more helpfull
