Yes chicks lay egg randomly, but player may wait till the sunset without moving. Eggs lain in 5min-10min all lead to the same displayed time(both rta and igt). If craft means no structure, you need to burn iron and craft bukkit by yourself, and farm for wheat too(It won't take long since you can kill skeletons for bone meal). If means ontain a cake from crafting table, they can come from village. It may be unsuitable on the level leaderboard, but also not an RNG-based run.

I'd like this category, but i don't think you should have limitations on how you obtain the materials, other than the cake itself, and timing should start on world creation, as it does in most runs where waiting makes a difference (any% random seed glitchless for example)

For create2obtain timing, it is only a comparation of luck. All the other material can be gotten easily in 5 min, and lots of time just spend on waiting for an egg
