I'm not going to shoot a very small yearling doe
Oldsmellhound, if I had only two days to hunt there are two reasons I would not feel bad at all about shooting a yearling doe. First, they are mighty fine eating. Second, if you take out a yearling doe you've eliminated that one deer from next year's herd. If you shoot a mature doe you've eliminated two or three deer from next year's herd - her plus the one or two offspring she will produce in the Spring.
