Chickens spawn naturally in the Overworld in groups of four above grass blocks with two blocks of free space above it at a light level of nine or more. Chickens do not spawn in deserts, snowy plains, ice spikes, snowy slopes, meadows, wooded badlands, jagged peaks, frozen peaks and stony peaks. In Java Edition, chickens are more common in sparse jungles. Chickens spawn individually after the world generation and 5% of chickens spawn as baby chickens. In Bedrock Edition, chickens require a light level of 7 or more to spawn and spawn in groups of two to four during the world generation.
