I've ordered a 5ft and 6ft hutch but non of the boxes are that size.

We have cleverly designed our flat-pack hutches and runs to fit in 2.5ft and 3ft boxes to make it easier for courier drivers to carry and discourage damages in transit.

Finding the instruction and screw pack (located in one of the boxes) will show how the panels go together to make up your 5ft or 6ft hutch.
