Before the Hen stage, an effect opens early once the pet has been killed by fire (Fire), killed by a Zeus x27 (Lightning) or killed by a planted C4 (Explosion). The locked button says: "Not old enough, unless your pet has faced worse." Valve's Sept. 22, 2026 notes: "Chickens now take damage from the Zeus x27."
