I'd really really love it if there was a way to tell if the eggs someone
offers you are fresh, old or spoiled. Not trying to trade, 'cause that's already there.
In my opinion, it breaks trust when, say, you're trading food for some creatu eggs, you get some offers and they're some pretty good, rare eggs. You accept, only to be distraught by the fact that this person has given you spoiled eggs!
This feature would be nice to implement when offering, too, so that you can prevent yourself from giving spoiled eggs.
