Bag of egg

This ordinary bag, made from stained white cloth, appears empty. Reaching inside the bag, however, reveals the presence of an ...EGG?. The bag weighs 1/2 pound.

You can use an action to pull an egg from the bag and do what you like with it, use it for cooking, hand it to someone in a show of support or throw it?

If you throw it up to 20 feet, flip a coin it may break on impact or it may cause the egg to hatch/activate immediately. If it is a creature, the creature is friendly to you and your companions, and it acts on your turn. You can use a bonus action to command how the creature moves and what action it takes on its next turn, or to give it general orders, such as to attack your enemies. In the absence of such orders, the creature acts in a fashion appropriate to its nature. All animals should be considered wild and may not remain in your party unless successfully tamed/befriended. 

You may need to roll a nature check to determine if you know what the egg is (medium difficulty)

Once four eggs have been pulled from the bag, the bag can't be used again, this regains 1d4 charges upon a long rest if kept warm.
