6 of one half dozen of the other the deer see them all the time and so on one hand they are used to their chatter on the other hand if another animal is sounding the alarm they will sometimes steer cleer. Being out there is the only way to know and if you see deer come in then they spook at the squirrels barking then maybe they won't come through that area at that time. Hard to say think like a deer be the deer.
