Time and Money.
If you don't have it, farming will be very difficult.
On a daily basis, it doesn't take much time. I just went out to feed the cows - 2 of them - one bale of hay and carried out 2 five gallon buckets of water. I checked the chicken coop and collected 8 eggs and didn't need to refill the automatic waterer or feeders. So the effort took 10 minutes total.
This weekend I'll add more sawdust bedding to the chicken coop, refill all the waterers and feeders, and will add leaf/pine needle bedding to the cow stall. Bob will split wood for a few hours. And stack wood on the front porch to be used for the woodstove for the week.
I'll do an inventory of the freezers, pantry, and root cellar to make sure I'm using up our preserved food evenly. I'll spray and monitor the camemberts in the cheese cave too. Organizing the freezers is important because the beef from our cows is coming on Monday.
So, this weekend we'll spend a few hours, but only a few minutes a day. If we had an extra $3k, we'd put in a hydrant in the barn, so I wouldn't have to lug water. For another $3k, we'd pave the driveway, so we wouldn't have to iceskate to the barn all winter long. Another $6k and we'd have a tractor to pull the stumps out of the orchard, so we'd be able to mow the weeds, instead of hand cutting all summer.
Even after raising the cows ourselves and paying a few thousand dollars a year for hay, water, and vet fees, we still have to pay $.70 a pound for the processing. So all in all, we'll pay plenty for our own meat, not including the time or costs of building the electric fence ($3.5k) five years ago.
I'm not complaining. I'm just done being some kind of doe-eyed silly person about farming. I like doing it, but time and money. You need both.
