As a child, Edgar spent much of his time sketching from farm life, and was considerably influenced by his brother, Walter Hunt, a skilful animal painter in his own right. By his mid twenties he had made up his mind to devote himself entirely to the depiction of farmyard animals.
His compositions, usually on small canvases, were mostly of farmyard scenes in which domestic poultry and their broods predominated; although calves, pigs and rabbits were often introduced. He worked in a meticulous manner not a feather or a hair was out of place. His style is immediately recognisable, hardly changing throughout his career.
Edgar was of a retiring disposition and seldom exhibited his work, preferring to spend his life with the animals he owned and lovingly painted.
Edgar was a great admirer and friend of John Frederick Herring Junior. When Herring died in 1907, Edgar was inconsolably bereaved and became almost a recluse, rarely leaving his farm. Edgar however was still very much in demand by his patrons. His patronage wanted uncomplicated images to which they could relate immediately and without troublesome intellectual effort. Hunt also incorporated an element of sentimentality to elicit the maximum emotional response.
He exhibited at the Royal Society of Artists and at the Walker Art Gallery in Liverpool.
