All kids love animals, and so many young storybooks revolve around the farm. Start planning your party by thinking of some fun farm activities. You will also want to add some games centered around farm animals.
Some other fun animal games and activities include:
Animal charades - instead of guessing a book, movie or character, have fun guessing animals
Freeze dance - where each time you start dancing you pretend you are a different animal
Singing Old Macdonald (For little ones! They love this!)
Reading a book about farm animals
Doing an obstacle course of farm activities - pitching hay, brushing animals, etc.
Create puppet shows at the party with farm animal puppets
