What’s the difference between an Ovation 56 and Ovation 28?

The only difference between the two machines is the size and egg capacity. The Ovation 56 is a larger machine and holds up to 56 hen-sized eggs or equivalent. Whereas the Ovation 28 holds 28 hen-sized eggs or equivalent.

The Eco, Advance and EX versions of the Ovation 28 match the specifications of the Eco, Advance and EX versions of the Ovation 56. The only difference is the egg capacity.
