keith, i have seen many a dink survive without mama around. the key is that tghe winter is not incredibly harsh. a good example is that we ween our calfs off of mama at 4-5 months. that is to ensure they aere very big. you can ween them at three months. i think cattle and deer are alike in many ways, including that they are ruminents. anyway, to your point, go ahead and add mama to the freezer, cause you won't hurt them dinks a bit. the onl;y timw i would suggest leaving the mamas, is during very harsh winters, and that would only be so that the dinks learn to forage through heavy sniow and such. whenh the does come into estrus they will ussually run off their fawns anyway. whack em and stack em.
