RE: how to hunt deer in this situation?
There are a few different ways that you can hunt an area like this.
1. You can hunt the food sources. Either you can scout around to find out what these deer are eating and hunt them there, or you can make a nice food plot and bring them to you.
2. You can hunt the water sources. I don't know what the water sources look like, but you can bet that if there is only one pond in the area that the deer will be there to drink every now and again.
3. You can hunt trails. The most productive trails will be between food and bedding areas. I know that you say that you don't know where they are bedding so you will have to make an educated guess.
4. Still hunting. This is not a bad method when you are clueless about the activities of the deer in your area.
