i use notepads. i put everybody's name (if i decided to name them) or put everybodys morph (for a lack of a better term) on the notepad. and i write the date, and keep track of defecation (when and what it looked like, ie diarrhea/normal whatever), when and what they ate, and when they shed and if it was a good shed or not so good, or assisted. and during breeding season, i make sure i write down who all i pair up especially if pairing a male with multiple female. if and when i actually saw copulation, ovulation, etc. i have downsized my collection alot, so it is alot easier for me now, but that is what i do
