Seconding this. Quit the world with 13 cows and MANY chickens in pens; come back to 8 cows and 5 chickens in pens. The cows were dispersed around the place, I herded 3 back in... but I don't know what happened to the chickens. In 1.4.2 on a server where their pens bordered on walls I'd sometimes see the animals' drops (and one or more animals missing) when their chunk re-entered memory, and playing 1.4.4 it looks like the issue still isn't solved.
