I was reading this yesterday morning and mowed one of the lower field sections later in the afternoon, about 8 acres worth. Sure enough I had a fawn jump up right when the bucket was over top of it, luckily it bolted away into the wood line near one of the ponds.
Second pass in that section same thing happened, I thought it was the same fawn. I dropped down a gear and mowed just that small patch thinking the fawn was coming out of the woods and laying back down.
After I got done with this area (about half the size of a football field I went out to finish the bigger area. Sure enough, momma and two twin fawns were out grazing in the same area.
Once I got done I started to head over to the backside of the pond to cut it but saw them standing over there in an access area I mowed a couple of weeks earlier - the entire area is about a football field size but hardly accessed by us because we aren't fishing it right now.. I figured I will let it be for a month and give the little critters a safe zone. It startled the heck out of me when it happened... as much as I hunt I would hate to run a fawn over, these things were about 20 lbs and tiny.
