Not 100% sure but I think all it means is that if a farmer needs to take some deer for crop damage (which they could do as long as I can remember) he can now designate one or two people to dothekillingfor him on his property.

I dont think the shooters can legallykeep the deer, it would either be picked up by the WCO or kept for the farmers personal consumption. I think the farmer is allowed to posess one crop damage deer for personal use at a time.
