Silas Merlin, one of the world builders of Paer Thura, has been hiding chickens throughout the Fairelands. Why? Because the International Poultry Association declared that the flamingos have had their spotlight for too long, and chickens can share some of the winged attention!
The hidden chickens cannot be interacted with, although they are fun to search and find, but fortunately they have all been herded into a gacha for convenient fowl acquisition!
Edit: there is now an additional chicken in A’Dracunas! Find it and you can get that one for free!
