I have not seen the fox lately but I have no doubt he's keeping an eye on us or more specifically the three hens in the pen.
Since the hens are no longer able to free-range the property I bring them kitchen scraps - veggies and fruit.
A few days ago I gave them the tips of grasses growing outside the pen and they ate every last bit. So now in addition to veggies from the kitchen I pick fresh greens for them.
I noticed patches of Miner's Lettuce growing outside the pen so I picked a couple. First they ate the flower, then the leaves, and then the stems. They liked it so much I went and got a few more.
