We already learned how to say dog and cat in ASL.
Now let's learn about some farm animals!
cow - With your thumb by your head, your pinky sticking out, and your other three fingers closed, wave your hand forward and back like a cow's horn.
chicken - With your right hand fingers in the G shape and your left hand flat, use your right hand like you are pecking seeds from your left hand.
pig - With your right hand under your chin and your fingers pointing to the left, wiggle your fingers.
Here is a helpful video showing these signs:
