About the dinosaur egg.

[BlackMonkey92]

I'd like to ask the producer to make the dinosaur egg into a dinosaur egg mayonnaise, not an ordinary Mayonnaise, the next time you update it. plz

Agreed. You might not even realize it's a big waste unless you pay attention to the item value.
For those of you who don't know, dinosaur only lay eggs every 7 days, so the value is the same as 7 chicken eggs to compensate, but it turns into normal mayo with the same value as that from a regular large chicken egg.

Only turn it into Mayo if it is a basic one, silver on up gives more selling the egg.

Only if you have the artisan perk I think.
A no star dinosaur egg is worth 350g and a gold star mayo which it turns into is worth 285g and 399g with arisan.

There's a mod called Animal rebalance that increases the value of the less common animal products like dinosaur eggs and duck feathers that make them a bit more worthwhile overall, though some would probably think it makes it a bit unbalanced.
