That would depend on the age.Looks like a Speckled Sussex cockerel. (So a he, not a she.) Could be wrong but the comb and wattles look very large and red for a lady Sussex.

Notice that despite the red comb and waddles there are NO pointy saddle feathers that would indicate male.

I agree likely Speckled Sussex. The other option mentioned Jubilee Orp... doesn't seem like right body type, but yes that was a good guess. They are very similar looking. Both beautiful! I like the Speckled Sussex.
