You can, and the eggs will be safe, since a smaller egg in a deeper cell is protected rather than at risk. What you lose is presentation, because chicken eggs sit low and the carton reads as underfilled. Producers running both birds usually find the appearance penalty outweighs the simplicity of one SKU.

No, and pulp handles both identically. Duck eggs have a slightly less porous shell than chicken, which is part of why they keep marginally longer unwashed. What matters is that the packaging neither traps condensation nor dries the shell, and fiber does neither because it regulates moisture rather than sealing it.

Send us a few eggs, or send accurate measurements of your largest regular egg at both length and maximum girth. Length alone is not enough, since girth is what decides whether the egg seats or perches. We seat samples in a production carton and give you a direct answer rather than an estimate.

Per carton, yes, because deeper and wider cells use more fiber and the larger footprint nests slightly less efficiently per container. Per egg sold, the difference is small against duck egg pricing. Buyers comparing the two on carton cost alone are measuring against the wrong denominator.

 Inside an outer box with void fill, yes, and the deep cell is an advantage because it immobilizes the egg. Movement and rotation damage the air cell, which kills hatch rate well before the shell is at risk. We make no hatch rate claims, since outcomes depend on transit time and handling far beyond the packaging.
