I currently use either:
Hatch year and clutch # - m or f - Morph name - # (in case I have multiples)
So as an example here is the ID for my Pastel Clown
1474-m-Pastel Clown-01

If the breeder didn't assign clutch #'s I then use month and day of hatching.
0714-f-Orangebelly Mojave-01

Once I start some of my breeding projects next year I'll assign clutch #'s to mine so eventually I'll have most of my family on the first type of ID.
I'm also using Reptile Scan to track feedings, shedding, cleaning etc.
