You don't, a mod should come along and close it for you.

This is not a duplicate. Here, animals are ACTUALLY leaving the area. I can confirm on 1.4.6.

This occurs for me in 1.5.1. It seems to occur only when the animals are crowded and the chunk is loaded. I have yet to observe it in action, but it only happens when the chunks are loaded and the animals are under pressure. It's also not just transparent blocks: I've tested it with glass and cobblestone with identical results.

That's being tracked on MC-2025.
