In other news, I forgot to mention another by-product of rain - weeds. Though I can't recall the names of the two I find most often, the ones I worked on today, bermuda grass, were the most invasive. It stretches out and sets roots most anywhere it touches soil. And the roots go deep, which means digging. And digging means... worms! The chickens ate well.
The bermuda is so persistent, it broke through fiber cloth and even black plastic ground cover! Bad stuff, it seems...
