Mine the spawner as if it was a normal block. The spawner will fall into your inventory. Make sure you meet the above requirements to mine spawners.
Spawners can be stacked. This technically means you are upgrading your spawner by applying another spawner to it.
The number of spawners in a stack will be displayed above the stack of spawners.
All ranks can stack spawners.
To stack spawners, simply place a spawner of the same type onto another spawner.
You are allowed 1 stack of up to 20 spawners per chunk. In other words, 1 mob type per chunk and 20 spawners per chunk.
