Create a highly detailed black and white vector pencil sketch illustration featuring a proud hen perched majestically on a weathered wooden fence rail in a vibrant farmyard setting. The artwork must be rendered entirely in monochrome using only black ink on white background with intricate cross-hatching and fine line work throughout. Develop the hen's elaborate feather patterns through meticulous layered hatching that shows individual feather details, wing texture, and the distinctive comb and wattles with naturalistic accuracy. The wooden fence should display rich texture with aged grain patterns, knots, splinters, and rustic character created through varied line weights and directional hatching. Include a richly detailed background featuring a classic red barn with vertical board siding, rolling hills with atmospheric perspective, scattered hay bales, wildflowers and tall grass in the foreground, and fluffy clouds in the sky using delicate stippling techniques. Add depth with additional fence posts receding into the distance, farm equipment silhouettes, and trees with detailed foliage using fine line work. The composition should balance the prominent hen in the foreground with the expansive pastoral landscape behind, creating a complete and immersive farm scene that evokes nostalgic countryside charm with museum-quality illustration technique.
