Yes, spy chickens. It's a joke I picked up on. Funny thing is, one time I returned to my house, with a wall around it, only to find that FOUR chickens had somehow gotten in! They were gathering intel about my defenses, I tell you! =P
Ah, yeah, I've heard of those. Haven't seen any, since none decide to go near the beach where I set up my base, but... There's always the full game, if I ever get it. =P
