Prized Animal Clone Bug

Make sure that your farm is full with adult animals, then move a prized animal from a prized animal shed to the pasture. An Animal Crowding Alert pops up and to the right of it, the game notifies you that your prized animal has been put in your inventory. That's a clone.

Now open the pasture and move the prized animal back to its shed. The message pops up again.

Go to the inventory and you'll find two clones of the animal you moved.

I've used this bug to fill my prized animal sheds with the best prized animals I have on my farm. Some that gives more prized goods and others that give higher XP.The bug can also be used to fill the pasture so that you can get fuel pump upgrades and keeper points in the journal.
