'The Red Wheelbarrow', is a poem by American poet William Carlos Williams. It was originally untitled and written somewhere in 1923.
In this poem, William wrote:
<h3><em> "So much depends upon a red wheel barrow glazed with rain water </em><u><em>beside the white chickens.</em></u><em>"</em></h3>
One way to interpret this is that much depends on these elements, these symbols of farming that are central to the preservation of life as we know it. In this poem, Williams attempts to offer concreteness of expression as a main feature.
Going back to your question, the answer would be: white chickens.
I hope this helps! Have a great week!
