Well, with all the livestock I've kept, I've never left anything to chance, especially with 'first timers'. I was fortunate many years ago to have a farm vet as a friend, he taught me how to deal with animal birthing problems, I am forever grateful to him! I note the change in behaviour patterns approaching the event and make sure all is prepared, you can tell when things are pretty imminent. Having had to deal with malpresentations in goats, malpresentations, retentions and stillbirths in sheep, I'm acutely aware that sadly things can go wrong, I would never forgive myself if I lost a mother through non attendance. I keep quietly in sight of the animal and observe how things progress, only intervening if and when really necessary. Most times things go quite naturally without any interference from me - but I'm there just in case. But also for me, when it all goes naturally and without problems, I have never tired of the wonder and joy of watching the newborn arrive and take their first feed with the mother 'talking' to them.
