I noticed that it's hard to manage chickens in 1.6.4. Even when you show them seeds, they don't stop running. When babies this is worse.
Environment
Java Version 7 Update 40

2 memory units of 1GB DDR2 SDRAM maximum in transfer rate 6400MB/s

I though that this wasn't the same problem as MC-22927, but now I see it is.
