I downloaded my world and optimize it as a single player world and it seems to fix the issue.

Mine picture is in vanilla Minecraft. It's not the problem and also mine is in a server and everyone on the server can see this problem. 

Sorry for not responding and it has been fixed. Not sure what version.

Wrong picture, sorry. Right one

This is also happening to me, I try destroying the building and letting light get in to update but doesn't work. 

Are u sure, like try it on a survive server. That how i got my friend to check it for me. Also have nothing in your main hand.

IK that but they push each other when none of them are clicking the w key.

I think the chicken part is fix but i don't know about rabbits. And the chicken started to drop the meat because they lava tick i think was off because in 16w02a it one shot the chicken when it didn't in 16w03a I think that why.

I'm very sorry I think it fix for some reason the chickens started to drop the meat again in 16w03a. After i reinstalled the file after my server crash.

That all i copy
