Emergencies happen, and when your homesteading, they become more complicated.
Over the years of farming we have had many (fortunately small) emergencies that have required we drop everything and go to the hospital.
This is hard to do anytime, but when you have lots of animals that need fed and watered, and cared for to stay alive, it makes emergencies even worse.
Having been through this many times we have learned some important lessons in preparedness.
First and foremost, when you begin any homesteading endeavor, you and your partner (if you have one) need to be on the same page. It can't just "be your thing" because one day your SO will need to give you assistance in getting something fed, watered, or kept alive.
Then you need to be sure to have enough supplies on the homestead to run it for at least a week. You can bet the day you run out of hay or feed is the same day the trip to the ER happens.
Finally you need to be sure someone is trained to do the jobs you do. If you have a partner, then be sure you both know how to do all the needed jobs.
If not, know the farmer friend you can call when things get tough.
I hope you don't have to deal with any big emergencies. But be ready and the big ones will feel smaller.
