well all depends on a lot of things, like if deer normally bed on the [property for the day , if so they will be moved off most likely
also depends on how big the property is, hw much they cut, if they leave tops ot take, or clean and stack them
most timber companys prefert o cut in winter here, does less damage to the landscape
typically deer adjust petty easy to things, but if too much disturbance is all day for many days they can move off till done or just visit it more only at night if it is a food source
lots of things to consider
but in a few yrs if they cut enough you will have more browse and cover, and deer like that
