You guys are seeing much the same as I am. If the winter has not been particularly hard, this can be a pretty restful season for those does. They may have a little fat left from year before, no one running around shooting at them, and the warmer days and shorter nights mean they are burning fewer calories and the sun can be a real blessing on a south facing slope. Then, on a good day, they can walk along the garden and munch the "deer lollipops" (tulip flower buds).
