HELP!... My Dog eats rocks..

So my 1 year old puppy (border collie/husky mix... Idk if that matters) eats rocks... Sometimes she holds them in her mouth, sometimes she swallows the rocks. She will throw them in the air and play with them, bark at them, and idk if they are talking back or what but she's like "I'ma eat you now!"

Is this normal? Or ok? How do I get her to stop? She has raw hides and elk antlers to munch on throughout the day as well as other toys like tennis balls and stuffed toys. She also runs into walls and dressers when she chases her tail... I'm assuming that's normal. Haha.. idk. Pic of my weirdo for attention.
