Killed my limit of 6 Fox squirrels about a week ago in WV. Seen one just at daybreak but didn't shoot to 9 and finished at 9:45. The day before I was deer hunting and seen them at daybreak and they stoped by 11. During deer season the week of thanksgiving seen squirrels all day long. I usually kill more time of year later in the morning to midday. I think because it is cold they wait to it warms up to go out.
