I can spawn multiple chickens on one block using spawn eggs.
What I expected to happen was...:
That the chickens wouldn't spawn in each other.
What actually happened was...:
A new chicken spawning on the same block as another chicken.
Steps to Reproduce:
1. Put a block 1 block heigher than the blocks that will surround the block to be placed. *
2. Grab some eggs and touch at the sides of the face of the block pointing upwards. By doing so you will not touch the previous chicken spawned in the middle of the block.
3. Check it out.
Note: it will be beter to surround the block with lava, this prevents the chickens from walking. They will stay on the block.
Fun fact: a giant chicken explosion can be created if you hit the chickens
