To answer your question, you should be very concerned with the wind, concerned to the point that if the wind is even the slightest bit questionable, you shouldnt hunt that stand. The deer might let you get to 60 yards of it, but getting within 20 is an entirely different ball game. Also just because this one deer doesnt seem to mind, altough i think she will when you are hunting her ( deer seem to know when the are safe and arent[:@]) other deer will certainly know you are there if the wind is bad and wont come anywhere near you.

The fawn will be fine, take the momma if you get a chance and let the fawn go till next year. Good luck with them
