There's nothing like hands on experience to figure these things out. If you have facilities (like a squeeze ) and some basic tools (pullers, obstetric chains, obs. gloves, etc. ) you can manage most of it, if it's something simple ( calf coming straight, heads out or close to out but she's just not getting it done, or the calf has one leg back).
If a leg is back and the head hasn't appeared it's not much of a trick to push it back a bit, cup the foot in your hand and bring it out. If you need to hook the puller up, put the chain loops just under the dewclaws and give another half hitch a little lower down. Take your time when pulling, keep the puller high and take a bit of a strain and wait until she pushes. When she pushes, push the puller downwards. When she stops straining, raise the puller and take up the slack again, repeat as requ'd. It's a good idea to kinda rotate the calf as it comes, helps prevent hiplock.
When it hits the ground make sure it breathes. I generally grab a piece of straw or some such and stick it up a nostril and tickle it around a bit until it does a kind of sneeze. That usually means it's on its way.
Of course, don't be afraid to ask for help, it's good to have experience there to advise you. But getting your own hands in there is the only way to get the experience required.
