A few days ago, we brought home 6 bales of straw in our small pickup just after dark when the chickens were already in their coop. We parked in the back yard, near where the chickens play, tarped the straw, and went in the house. The next morning I let the flock out, and returned to the house. The next time I was outside, there were 2 green eggs in a sweet little nest, in the truck bed; under the tarp. So, my question is - how did they know the straw was there? Can chickens smell that well? Or what?
