Unless you have them fence in alone by them self, there is no way to tell how many fawns a doe has except through a DNA test. Whitetail does are great mothers and will let fawns, other than their own, nurse.
Young, first time mothers, generally have 1 fawn and then afterwards normally have twins. Having 3, or even 4 does happen on occasion.
I know it depends on the location as well. In Alabama our deer heard is so large that quite a few does on our property from year to year have triplets, but most of them usually drop 1 or 2.
We even had a 3 legged doe for the longest time who had triplets every year until one of the IDIOT hunters that USED to be the club decided he wanted to shoot her. It was a shame. She was a great producer. She usually had 2 bucks out of the 3.
Want a quick and inexpensive call for Moose? Take an empty 32 ounce coffee can, and make a small slit in the bottom, only about a quarter inch. Then, take one of those really big red rubber bands, the ones that go around big folders. Cut the rubber band to make one long piece.
Now, thread one end of the band and tie a knot on the outside of the can so it won't pull through. Cut the band off on the other side so it is even with the top of the can.
Now, wet your finger,...
