The Lava Chicken Music Disc has been introduced in Minecraft as part of the beta version 1.21.7, serving as a hotfix for the Chase the Skies update. It features an 8-bit melody remix of "Steve’s Lava Chicken" by Hyper Potions. To obtain the disc, players must defeat a Baby Zombie riding a Chicken, known as a Chicken Jockey, which has a natural spawning probability of 0.4875% for the Baby Zombie and 0.2375% for the Chicken Jockey. Players can also summon a Chicken Jockey using the command: /summon chicken ~ ~ ~ {Passengers:[{id:zombie,IsBaby:1}]}.
To acquire the disc, players should locate or summon a Chicken Jockey, defeat the Baby Zombie while keeping the chicken unharmed, and collect the disc upon the Baby Zombie's defeat. The disc can then be played in a jukebox.
