I had a small yearling doe come in 2 nights ago and the entire time she was moving around in front of me she did a continual grunt. It was not a bleat but a throaty grunt. I am pretty sure she is the yearling to the big doe I shot a week earlier in the same area. I have never heard a doe grunt like she did. She was right under me and I looked at her head for nubs to see if she was a young buck but I did not see any. Is this usual?
