Would you rather shoot the doe and hope they stick around like they should and as I beleive they do, or would you rather not shoot her and have her chase them off within the next year when she has new fawns? The biological idea behind it is that she will chase them out of her home range to reduce the chances of imbreeding but then again the doe in the other home range, on the nieghbors lets say, will kick her buck fawns into your range so really either way mother nature has her own way of mixing bucks and does around so who knows. I personally will shoot the doe but I don't go looking for only does with buck fawns. I shoot a few mature does each year because we need em shot where I hunt. WCL
