ガチョウ、七面鳥、バンタム用の卵パック

No, and we would advise against one. A carton with cells of several sizes wastes space on every cell that is not filled, and it only works if a producer reliably has one of each bird on hand at packing time, which almost nobody does. Separate cartons per bird is the practical answer.

Fiber quantity and freight. A goose cell uses several times the material of a chicken cell, and the larger footprint means far fewer cartons per container. Against goose egg pricing, which is substantially above chicken, the packaging cost per egg sold remains proportionate.

Rarely at commercial scale, and the economics explain why. A turkey hen lays far fewer eggs than a laying hen and the bird is worth more as meat, so the eggs are usually set for hatching rather than sold. Most of our turkey carton demand comes from breeders shipping fertile eggs.

Separately, and there is no way around it. The size gap is too large for any single mold to bridge without failing one bird or the other. Producers running both keep two carton lines, which is normal in mixed specialty operations and costs less than the breakage from compromising.

No, and the mismatch runs the other way from what people expect. A bantam egg at 25 to 35 grams is two to three times the weight of a quail egg, so it will not seat in a quail cell at all. Bantam needs its own geometry, sitting between quail and standard chicken.
