I am making a farm with a barn and everything. I have sheep for shearing and chicken for... well, chicken (and eggs) and I'm wondering if you can milk a cow.
If so, how can I milk cows?
Create a Bucket, and Right-Click the cow with the bucket to get a Bucket of Milk.
Drinking Milk won't fill the hunger bar, but it will remove any active effects on your player (such as Poison, Hunger and even positive effects like Strength).
Milk can also be used as an ingredient to make Cake.
Milk is a type of "drinking object" in Minecraft. It cures the players negative effects such as poison, and hunger. But beware it also move positive effects! You can also use milk for crafting cake, requires 3 milk buckets.
To milk a cow, you to make a bucket using 3 iron ingots in the crafting table. Then find a cow and Right-Click the cow to get a Milk Bucket.
You can also milk Mooshrooms using a bowl made of 3 wooden planks [Any type]. When you milk them, you get Mushroom Stew which you can eat for a few hunger points. Mooshrooms are found in the mushroom biome, and island where there are mushroom trees and some normal world stuff like caves.
