Just killed a doe yesterday, she seemed to be lactating. I don't check to see if they are pregnant or not, but often they are lactating. This one had some clear liquid in her teets, not the normal milky color. It wasn't puss or anything, and she was healthy so don't know what that could have been. In my area there are quite a few does, this one had three or more with her, and possibly a buck back in the woodline. Most years I take one or two does, and/or a buck or two, as I am hunting for meat, my neighbors used to hunt more often, but it seems to me the shooting has slowed down the last few years, while the deer population seems to remain about the same.
