 Chicken spawn on dirt and grass blocks, have 5 HP and are friendly. When killed or dying
 they drop meat, which can be eaten or cooked and probably some feathers. Also they drop

 Adds sheep to Minetest (requires Creatures MOB-Engine).
 Sheep spawn only at day-time and are friendly and remain around 5 minutes in the world.
+There are four different wool colors: white, grey, brown and black.
 You can tame them by feading them with wheat. If there is grass they eat the grass
 and regrow wool that way. They will follow you if you have Wheat in your hand.
 Sheep have 8 HP and drop 1-2 wool when punched or 1-3 wool when using shears.
