I lived in serious farm country for 30 years. I had my own 50 acre place (which didn't have crops planted on it, and was thus referred to in the South as a "place").
Real working farms always have rough gravel driveways leading up to the house and other buildings, so no smooth pavement.
And, the business of agriculture is an extremely messy, gruesome, day to day, affair. So working farms are not neat and tidy as you might see in pictures and movies. Stray pieces of large and small equipment here and there, old tractors or row crop machines (that "someday" will be repaired) are parked askew in various places, with tall weeds licking the tires, worn out gray wooden sheds that have been repaired and re-repaired for 50 years, in convenient locations, and houses that are sad and neglected because the farm work always has to come first.
Typically there are two or three mixed breed dogs (always with a dash of beagle genes) sit on the porch or under an old tractor. And there will always be a pick-up truck, not totally beaten up but definitely worn. Cats are generally not welcome and are often shot on sight. (Stray cats can multiply like rats and kill almost all small game in the area.)
Interestingly, you almost never see an abandoned junk car on a farm, as you always see in hillbilly country. Farmers spend all of their time working on crops and farm equipment and have no interest in trying to get a junk car "going again," so when one is on its last legs they sell it to a friend or relative for whatever they can get.
Most farmers I knew didn't raise chickens. As you know, they are alot of work, extremely stinky, constantly under threat from fox, coyote, weasel and bobcats, and the days of slaughtering a chicken for dinner are long over. (Takes an hour to kill, pluck, and dress one. And the eggs you can get are not worth the money you spend.)
Extremely few working farms have a horse anymore. They are all big-time trouble, very expensive to keep, and contribute nothing to the razor thin profit margin.
Very few large areas of patchy weeds or woods are left on any real farm these days. Sadly, they clear, level and plant every square inch of ground they can, often right up to the edge of the road pavement. As one weary farm wife told me, "It's all about production."
Farmers always wear hats. 99% of the time, it is a baseball type hat, from the feed store or tractor dealer.
Unless it is a dairy farm, the only type of cattle you will find are "feeder calves." The large dairies have to keep their milk cows pregnant most of the time to keep the milk coming, so every few months they sell the bull calves, for $100 to $200, when they are only a couple of weeks old. You can buy them at the local livestock auction barn, or often by just calling up the dairy farm.
Farmers buy these, and their wives bottle feed them for a month, then put them on sweet feed, and then grain (corn), and then they are neutered. When they reach the age of about 8 months, or 500 to 600 pounds, then the ratio of the weight of the corn you have to feed them, to the pounds of weight they gain from the corn, really increases, so it is not economical to feed them anymore. So, they are all loaded up and taken to the livestock auction to sell, generally for only $500 to $700 dollars. This is why when you drive by farms, you will see 20 or 30 medium sized steers, all of the same color and weight.
Hope this gives you some ideas, if you want to depict a real farm. Your wife and kids may want a fantasy farm though. :-)
