Everyone knows that chikn lay $EGG, and Roostr squirt $FERT. The need to rhyme is stronger than we are.
Roostr produce the all-important $FERT—a token that can be used to improve FarmLand reward yields among other things. For more information on what $FERT can be used for, see the section on $FERT.
To produce $FERT, Roostr need to eat $EGG. These protein-rich ovals pass through the Roostr’s digestive system, helping them grow bigger and coming out the other end as $FERT.
Roostr bring added complexity to the Chikn game and give players the opportunity to optimize their Farming strategies. With the rollout of Foraging introducing new ways to spend $FERT, Roostr themselves have become even more important in the broader meta.
