Index cards. I write down the ID for the ball on the top of the card, for example 05NF01 (2005 Normal Female-01) or 06CinnM01, 06PasJunM01....etc. Then I make a column for the date, one for feeding item, blue, shed, weight, and an other comments column.

I tried Degei for a while...but got too lazy to go in and update the records on the computer everytime I noted a shed, or weigh snakes, or fed....the cards are right on the bins. Keep it simple.

If you're dealing with a lot of snakes barcoded computerized systems come in handy I'm sure.
