If I understand you correctly, you seek something to use as a flag and a seal, but not necessarily as a coat-of-arms on a shield. Actually, flags and shields are often related, and a flag is simply the shield 'bled' out into the quadrilateral shape of the flag. I have noticed that most places adopting civic arms tend to be overly eleaborate, creating a 'fussy' and unsuitable image. I would recommend simplicity.
Since you place an emphasis on farming and the pride of the natives of
Capron, I might suggest a rooster ('cock') as a basic element. This represents both agriculture and pride. If the rooster was set against a sun, perhaps a 'sun in slendour', this would also reflect the way of life in farming (up with the sun, the importance of weather to farming), as well as a sense of optimism and hope. A 'sun in splendour' has 16 rays, alternating between straight points and wavy points. A couple of examples are at:

The rest of the flag could be blue, or anything except white. Blue seems suitable for a sun in the sky.
The sun and rooster could be used as a seal, and, if desired, a coat-of-arms could be derived from the flag, with a rooster appearing again as a crest. I would blazon this (help me out here fellows) as: 'azure, upon a sun in splendour or, a cock of the genus? _____ proper, in base the date '1888' argent'. That is, you would have to be pretty specific as to what kind of rooster it was. 'Proper' means in its natural colours. If you want to make the rooster one colour (not white), say black ('sable'), then you have to specify the colour of the comb and wattles ('combed (or crested) wattled and jelloped'), say, red ('gules'.) Also the beak and spurs. So, it could be 'a cock, sable, combed, wattled, jelloped and armed gules'. You can't use a white rooster as the term for white (let's not debate labels here) is argent, or silver. The sun has to gold, and you are not supposed to put a metal on a metal. (That's why the field cannot be white.) However, if the rooster is of a particular kind that is naturally white, you can use it, but it would be 'proper', making it alright. The date, 1888, below the sun, could be white (argent) as it would be on the blue field.
The seal could be two concentric circles. In the inner circle would be the sun with the rooster on it, and in the space between the rims of the circles something like, "
Seal of the Town of
Capron, ____ County,
Virginia - 1888"; with the '1888' in the centre of the bottom.
Consider (and be explicit) about the dimensions of the flag. It could be 2 by 3, (any vexolligists around?), 3 by 5, 2 by 4, 1 by 1, etc.; but should be defined.
