no man, if you feed them with a balanced food and pasture they are okay! it's from the nature of the dary heifers be curious and eat attractive plants and be looking for food tough beeing well fed. but maybe they are demonstrating an action of stress by beeing kept in a small place or in a place with boring noises or something like this.
Try to improve them in a special bigger area far of these things.
i hope it help you, thank you!
