I am having a heck of a time making pens for sheep. I have used all fence, 3 walls and a fence front, even built underground pens with double high fence front. But my sheep seem to keep finding a way to escape. Has anyone else had this problem, if so how can I fix it?
Meh. Sheep are crazy. They lag and glitch and stuff and sometimes get out. I recommend making a room with your sheep farm hugging the wall and only one door into the room.
Fences in general are buggy in Minecraft. I had an issue with them in Single Player Minecraft a while back. I recommend solid blocks instead
