How do I understand egg-wise?

[english-learner]

I may not be as old as I could be (and will become), but, egg-wise, I am most
definitely not young.
Although, they seem to be on strike egg wise, so let's see.
Egg-wise, Easter is the most important day of the year.

What's the gender of the speaker?

Egg-wise, Easter is the most important day of the year.

Wild guesses:

1. I may not be as old as I could be (and will become), but, in terms of how much longer I'll remain fertile, I am most definitely not young. (Of a human female.)

2. Although they don't seem to be laying eggs at the moment, so let's see. (Of hens.)

3. In terms of eggs, Easter is the most important day of the year.

(I would interpret 'egg-wise' as 'in terms of eggs' in all three examples.)
