The chicken cage is a quest item used in the One Small Favour quest. Seth Groats requires five chicken cages to hold the chickens in, and asks the player to give Horvik three steel bars that he owes to him. After giving Horvik five pigeon cages and the herbal tincture and breathing salts, he will create the chicken cages. The player must then take the cages to Seth Groats to complete the next step in the quest.
If the player loses a cage, it can be replaced by giving Horvik 100 coins and another pigeon cage.
