There are any number of animals you can make out of eggs. The more traditional ones are chicks/ducks from yellow eggs, lambs from pink/orange eggs (with cotton balls), pigs, doves, and bunnies from blue or purple eggs. Then you can make bees from yellow eggs, hippos from purple eggs, bears and puppies from brown eggs, and frogs from green eggs.
All you need is some scrap construction paper, cotton balls, felt, sequins, feathers, permanent markers, pom-poms and any other crafty scraps. We used white glue for some parts, but I would advise hot-glue or tacky-glue.
The kids seemed to really like the idea of this craft, but the younger kids had a bit of a hard time with the glue not sticking fast enough. Overall, a very fun project!
