Pigeon-Wars

To explain the background to this whole story I have to move a week or two back.
I live in a big block building and I have a little balcony. I dont really go there much because theres not much space to do anything but stand. So I never really went there at all, besides during summertime I have a mosquito-net up.
BUT the other day I saw a pigeon sitting on the ledge so the curious me went to see whats going on. I ripped away the net and stuck my head out  - low and behold - there were 2 pigeons huddled in an empty flower-box looking at me with horror in their eyes. I had barged into their new home.
Well since it was chilly outside I thought to be nice and let them be there.
Today when I was coming home I saw 4 pigeons, yes 4 not 2, sitting on the ledge of the balcony. I ran upstairs, opened the balcony door and saw...poop all over the balcony floor.
So I scared away the pigeons, threw their flower-box (by now it was already filled with poop) to the big bin behind the house and as soon as the poop on the floor freezes, I can shovel that away. Sorry for the graphic descriptions, my Dear Void.
And those pigeons must never return, because the vengeance will be mineeeeee!!!!! ( Well, not really)
So the moral of todays story is - Nobody poops on my floor and gets away with it!!!
