I guess perhaps I am lazy or stupid or something.... I dont keep long term records, the front of the glass door incubator has the war plan on it, but as long as everyone is eating and doing well, I dont worry about em..... I guess it could be that I am working with a smaller number of animals (between balls, boas, carpets, and sd retics I only have around 50 animals not counting babies) I cant imagine the time it would take me to record all of that information and what would I do with it..... I know each of my animals well, and can tell you who hasnt eaten recently what females are possibly gravid just by walking through and pointing at tubs. I keep more careful records on hatchlings but even those are as simple as putting a + for a feed or a - for no feed....
