Minecraft PE players spend a lot of time searching for ore in caves. But there is an alternative that can save time. To do this, download the Nugget Chickens addon from the link at the end of the article.
After installing this add-on, seven new hens will appear in the game. But they differ from standard ones in that they carry nuggets instead of eggs. There are nuggets: gold, diamond, emerald, etc. Collect three eggs and get nine nuggets from them. Then put in all the slots of the workbench and get a full ore.
Build a farm and collect these feathered mobs there and you will no longer have to spend time running errands to the caves. Just remember to enable the experimental game mode!
