Many of you probably know about the trick where if you take a Lead, attach it to a chicken, then hook that chicken to a fencepost that is floating in the air, you can get the chicken to just hover there, and if you got loads of them it's a very efficient egg farm, if you got hoppers it is totally automatic.

But my question is, is this allowed? Cause I am not sure if it was intended by Mojang, or if it's a bug c:

You are supposed to be able to hook all mobs except for villagers and bats onto leads and have them lifted, drug around, flown, etc.  Hope this helps.

Indeed it would be, but perhaps you forgot that the mob clearance would kill the chickens right?

I think a mob attached to a lead won't despawn
