Creating ID Numbers - How-To?

[SnowShredder]

I'm only on my first clutch but this is what I did

Last two digits of the year clutch was laid; gender (M or F); clutch number (each clutch will get the number after the previous one like 1, 2, 3, 4 etc for forever); morph; unique number for that specific baby in that specific clutch.

So for my first clutch I had 5 babies and this is how their IDs go (on a flash drive each clutch will have a folder Clutch 1 clutch 2 etc, and each baby will have a folder inside the clutch folder labeled with their IDs)
