The reason I'm showing that is 1) Because I think it looks cool and 2) Because I think this is directly tied to the number of eggs a hen lays as well as the eventual survivability of those hatching chicks.......We're looking at a main food source in those last pics......How much of the landscape provides that kind of insect food source in that density??.....The answer is likely a portion of our equation for nesting success.....

Dont forget the soil organic matter is playing a big role in this too......That's where the foundation of the insect food web begins.....and that begins with carbon.
