Those 'new' hens have been six weeks in a separate pen and coop from the
eager rooster. This will soon change, along with the landscape.
Can anyone explain why hens make such good rototillers? Dad used to think hens destroyed any given patch of grass due to excess nitrogen in their droppings. It figures a chemist would think of sh** like that.
But the theory is indeed plausible, citing the fact that birds don't have separate urine and excrement; both join together when emitted.
As to the expunging of turf-grass, watch 'em sometime. They'll scratch the piss out of it.
