i just got a new ball python female and about an hour after haveing she started rubbing her nose on my hand hard. then i put her back in her box to take her home and when i pulled her out again it looked like she had something in her mouth so i got the tweezer to check it. i lifted it a lil bit and it was her skin. i soaked her in warm water for about 10 min and then her head started to shed down to her neck. she rubbed it off tho but she is still sheding. the only thing about this i didnt get was that she didnt show any signs of sheding altho she was dark. i thought it was just her patern tho, but her eyes werent blue and her belly wasnt red. is this a bad sign?
