I agree with ddrdaven - you really need to look at your property and the deer herd in your area. If you have a lot of does, shoot away. If not, be more selective.
My personal experience has been on our property that no, you will not hurt yourself by harvesting does early. We have many, many, many does - and shooting a few will only make the rut more active. But honestly, I don't know if we could shoot enough to cause that to happen - bucks have plenty of breeding opportunities with the number of does we have in our area so even if we shoot a few there is no reason to be fighting over the girls.
