Everyone has thier own method. I really new to redo my spreadsheet and update tags/labels. I'm not using my system like I should but will need to begin asap with increasing numbers of hatchlings. My idea was fromKJ Lodrigue (KJUN Snakehaven)....I think I've changed up his way a bit, BUT it works for me (thats the key- find something that works for you)
More less:
FEMALES are "named" alphabetical letters... start off with A-Z...then you can switch to TWO letters like AA, AB, AC, AD, AE etc.
MALES are "named" numbers 1, 2, 3, 4, 5 etc.
Make an excel spreadsheet to keep up with info (age, bloodline, hets, etc.) for quick reference.
"naming"/labeling babies is easy... breeding female AE to male 32 would give you LITTER AE32 you can even add the year at the end of that if you wanna get fancy. Litter AE3206 would be the 2006 litter from female AE bred to male 32
From there you can take things further if you want by labeling individual hatchlings...make it something you remember... you can always use "m" for males and "f" for females
Example:
AE3206M4 I would interpet that as the 2006 MALE hatchling #4 from the pairing of female AE to Male 32
If someone emails you two or three years down the road about an animal (AND THEY STILL HAVE THE ANIMALS NUMBER/CODE) you can easily tell them everything they need to know if they've forgotten it. You'd know it's a 2006 male...looking up the parental info from your nifty spreadsheet, you could tell them what the animal is het for along with parental bloodline info.
Hope that helps (it made sense to me.... just think up a way that works for YOU).
