How do you keep stock?

[Lapithicus]

I don't keep track of what I have, but I do put a label on each with the date I put them in my humi and where I got them. I use a cheap label maker set on the smallest font - works pretty good except for the cello-less, then I have to cut them down and put them on the back of the band. I like to know how old they are, especially when I buy duplicates.

..found a box of dirty rats I didn't know I had.

Very nice. I wish I had that problem.
