Need help with fence posts
So just a quick back story to get you guys caught up to where I am right now. Two weeks ago my cousin and I started digging the holes for my fence posts. 10 inch diameter and 3 feet deep. I had rented an auger for the day $150. After 9 hours of fighting we got 4 holes dug out of 20. The whole neighborhood is built on top of shale rock. So for the price for me to rent the auger again for 2 more days and a jack hammer to brake up any rocks we run into. It was cheaper to hire a guy to come dig the holes for me. The only problem is he only has a 6 inch diameter auger bit. I was planning on filling the holes with concrete but now I am afraid that with the 4x4 post in the hole there wont be enough space around the post to have enough concrete to make it strong enough that it wont crack. So should I stick with concrete or just back fill the hole with dirt? I am really at a cross roads here.
