In this dream I'm standing in a farmyard next to the pen where we keep all the various birds we raise.  (Not in real life.  Only in my dreams as I have a dreamland farm.  Cool, huh?  hehe)  Inside this pen there are chickens, geese, and ducks.  No particular breeds, just a variety of them.  One thing I notice right way is that, inside this pen, there is literally no peace, no calm, no order.  It's a mad free for all.  Why?  The pen is swarming with mice.  Even more interesting, all of the chickens, ducks, and geese are chasing after and attacking, and even sometimes eating the mice, and the mice are doing likewise in return (attacking, but not eating in this case, as they're not big enough) to the chickens, ducks and geese.  The dream ends there.

Interpretation:

I believe this was God showing me that the enemies of His Kingdom, and His children, are in total chaos and thus are turning on one another.  Here's the reasons I believe that to be the case.

1.  I'm not participating in the dream.  Merely observing.  Thus it's not about me.
2.  Geese represent manipulative, selfish people.
3.  Chickens represent cowards.
4.  Ducks represent noisy or boisterous people. (ie, prideful)
5.  Mice represent detestable or cursed things/people.

All of those things (2-5) would be of Satan.  So, if all of them are attacking each other, that to me says that there is absolute chaos in the camp and kingdom of Hell, and they are now turning on each other, which we can kinda see in regular life.  As such this dream, to me, indicates and confirms that it's an absolute zoo (ref, animals in a farm, lol) right now in the camp of the enemy. :)  Anyhow, I hope this encourages you today.

Oh, and PS, do you now understand why I chose that corny title? ;) :D
