Expected Result

It happened when i was trying to create an mob killer.
The chickens began to just stop with the fall-down animation and didnt fall into the void that i wanted to happen. I also saw that one of the chickens fal collided in the wall so i think the collision pushed the other chickens away but there got forced to go to the chicken by the machine belt.
