That's the susquehanna river. They don't stray too far from the coop right now even if I let them out in the yard they just try to get back into the run. I hope this summer they head down by the water. Lots of bugs on the riverbank! I'm still very new to the fermented feed myself. Basically it's just feed soaked for a few days in water. So that it ferments and kinda pickles. They go bonkers for it and it's supposed to be real healthy and make them eat less. Mine don't seem to eat less, but they do love it. There are a bunch of threads on here about it and on google. Might be worth checking out.
