I was done several things over the years, mostly i got a paper I print out wit heach snakes name ( on a line ) and set it so it devided by 4 and jusr put a letter in that week for each activity I had to do/they did.
example :
ID week 1 week2

snake n fpsc fpc

Letter were for what they did
feed ( ate)f
poop P
shed s
clean cage c
when I breed I have a index cage that I mark locks and who with who
like
butter with normal n
locks seen on 12/3,12/8, 12/12, type deals . this way when I seprate them the card stay with female so I can remember who is being breed to who.

Right now with all my snakes with mom I no able ot keep record s well cause she 100miles away . but I get phone calls almost daily .( she can't ID the snakes too well like het from normals )
