Two rabbits spawn instead of one

[QuantumSoul]

Hello,

My block summons a rabbit when generated but

1. There are always two rabbits instead of one

2. It spawns in the side of the block and thus suffocates. How can I make them spawn in the middle of the block ?

 

My block:

Spoiler

    @Override
    public void onBlockAdded(BlockState state, World worldIn, BlockPos pos, BlockState oldState, boolean isMoving)
    {
        super.onBlockAdded(state, worldIn, pos, oldState, isMoving);

        if(worldIn.isRemote)
            return;

        RabbitEntity rabbit = new RabbitEntity(EntityType.RABBIT, worldIn);
        rabbit.setRabbitType(1);
        rabbit.setCustomName(new TranslationTextComponent("nameTag.binarymod.white_rabbit"));

        BlockPos.Mutable nextPos = new BlockPos.Mutable();
        for(int x = pos.getX() - 1; x <= pos.getX() + 1; x++)
        {
            for(int y = pos.getY() - 1; y <= pos.getY() + 1; y++)
            {
                for(int z = pos.getZ() - 1; z <= pos.getZ() + 1; z++)
                {
                    nextPos.setPos(x, y, z);
                    if(worldIn.getBlockState(nextPos) == Blocks.AIR.getDefaultState())
                    {
                        rabbit.setPosition(x, y, z);
                        worldIn.addEntity(rabbit);
                        return;
                    }
                }
            }
        }
    }

 

Thanks in advance.
