Tallbird Eggs can be found in Tallbird Nests. Upon collecting the egg, the Tallbird that owns the nest and all nearby Tallbirds will become aggressive toward the player, chasing them for a short while. During nighttime and sometimes during the day, Tallbirds will curl up and fall asleep on their nest. The player can push the bird and collect the Egg, however this will wake the Tallbird. If the nest's Tallbird is killed and the Egg is left untouched for a few days, it will hatch into a new Tallbird. If the Egg is placed by a fire, it will change into Hatching Tallbird Egg, and can be hatched into a Smallbird (see Hatching Tallbird Egg for details).
A Fried Tallbird Egg is made by cooking a Tallbird Egg over a Campfire, Fire Pit or Star. It can also be used as an ingredient in a variety of Crock Pot Recipes. Unlike raw Tallbird Eggs they will expire and stack to 20.
When a Tallbird Egg is picked up, examining it will give the standard quotation based on the last state it was in when on the ground. For example, picking up a Tallbird Egg when day comes after it was near a fire will result in its examination indicating it is too hot.
