12-14 does off 1800 acres should not have any significant affect on your overall population assuming you’ve got good fawn recruitment and the people around you aren’t just blasting every deer they see all season long. With only 1800 acres, your deer are your neighbors deer and your neighbors deer are yours. You really need to look globally at what is going on, not only on your property but also what is happening on all the properties in the immediate area around you. Evaluate you harvest and management goals as well as your hunter expectations, with regard to deer sightings, and make your decision from there.
