So, I built me a mob trap, and this is the collection room (it's a work in progress, so it's rather ugly right now). The problem is, I keep getting chickens spawning in this room, but from where? The chickens are annoying because when I idle, I come back and they've pushed me away from the collection area at the foot of the stream.
Please FP, tell me where in this room the chickens are spawning?
