The fawns will be fine, i have read that once they lose their spots, they will be able to fend for themselves with no problems what soever, although i would think that even fawns with spots that have been weened off of their mothers would survive. Im planning on taking out 7 does this fall, have tons of people who want the meat and my family alone will eat 5 deer no problem. We also have a seriosly out of balance doe to buck ratio so im trying to do my part. Someone also mentioned it and i agree, if i can shoot a doe with button buck that looks like he will make it, i will. That button buck will be pushed out of the mothers home range and the chances of you seeing him ever again go down drastically.
