GaTH,
I had my hardwood bottom in Spalding County, Ga select cut about 4 years ago. The turkeys were literally watching the equipment work. They began cutting right in the middle of the season so I had to work around them. About once a week the loggers would tell me about seeing a gobbler while I was at the other end of the property hunting. I was able to get on one bird that they had seen while working. Just couldn't close the deal. I think the birds tolerate the disruption fairly well and will return to normal quickly after the logging stops. Good luck.
