I have a motion activated solar security light that I move around that I move around with my chicken tractor. Last night it activated for the first time not once but twice, causing me to get up to investigate each time. No sign of anything amiss, the birds weren't agitated when I checked, only somewhat perturbed by my shining a light in their eyes. Would a light scare a varmint away? Raccoon, Skunk, Opossum, Fox & Owls are all possible night time predators here. Although rare, because my yard is fenced I have seen Fox & Opossum in my yard in years past. Thoughts? Thanks!
