The Avian Placenta is an Item that can be found within common locations, including choice enemy Camps, given by Spouses, and rarely as a reward from Seasonal Festivals. Upon being picked up, all eggs collected will yield 3 to 8* Fertilizer each. This allows players to further utilize Chickens or Turkeys for Fertilizer collection far more from their original sums provided.
*Further testing is needed to prove these numbers.
Compared to other means of collecting Fertilizer, Avian Placenta is the most dependent on other variables. If the player already has large amounts of Chickens or Turkeys or both available, Avian Placenta can serve as a powerful source, potentially providing hundreds of extra Fertilizer each day. Prioritizing taking Chickens or Turkeys from Camps or finding Fertile Eggs can be of a great help. In addition, it is somewhat dependent on the amount of time the player has, due to how Chickens and Turkeys will produce more overall eggs with more time. This can make playing as Thyme especially valuable in that regard. Otherwise, if the player is unable to satisfy these factors to a great extent, Avian Placenta can end up being less effective than other means of gathering Fertilizer.
