I burn 7 cords of white birch a year to heat this house. I use a good chainsaw to buck up firewood. A good saw reduces the time and effort to cut the wood. Keep your chain sharp, stop cutting if the chain is even a bit dull and resharpen. I find sharpening easiest by placing the chainsaw bar on a vice. Sharpen each tooth and inspect the chain for irregularities such as broken rivets. Adjust tension.
I use a 5 pound axe for regular spliting, and a heavier maul for stubborn wood. I use a pickaroon to move wood around. This tool will save your back and your strength.
This is alot of wood and I am not exactly young and my health is bad, so I spread the work through the entire year.
Logging truck delivers 10 cords of 8 foot long birch. Then I buck it up and split it. I may do only an hour a day. Some days I only cut up wood, other days split or do both. When I am in better health I pile wood. Piling wood is by far the most difficult task- hard on my back, neck and stomach.
