I'm assuming this will very quickly need an ecchi tag but I guess technically right now it's just weird.
@HDMI1: This is pedantry and not of real substance, and I'm not even sure I've followed the conversation correctly, but at least in the context of food eggs, "fertile" would definitely mean one that has
been fertilized. (And I just now googled it to make sure I wasn't crazy.) Which makes sense; an unfertilized chicken (or reptile) egg that has come out of the bird (or reptile) is, to the best of my knowledge and belief, also no longer
capable of being fertilized.
Though I would have said there was the possibility of a translation issue—which I think there was, given that the current text now says "unfertilized"?
(The necessity of the text specifying it as unfertilized is of course theoretically debatable, but given the tone of these two pages I'm going to go out on a limb and assume it was indeed to get the audience's mind in the gutter in reminding everyone about the possibility of baby-making)
