Definitely make a call to you DOW office. I wouldn’t expect them to do anything, but they do like to track lion locations/sightings especially when in close proximity to people. This could be needed later if the lion makes moves on any people/livestock/pets they will more easily be able to track it. Generally hazing of habituated wildlife is supported in CO. Any non-lethal means to threaten or scare it. Lights, air horns, etc. whether or not electric fence is permitted depends on local zoning and ordinances, I believe in some areas it’s deemed a wildfire hazard. Mountain lions are opportunistic and will hide out in hopes you or another animal will get close enough to make a move. Please watch your surroundings very closely anytime you are outdoors. This Feb. was the snowiest on record in parts of the state, animals are hanging out in strange places and hard up for food. Secure fencing is best you can do for your flock. DOW May have some more ideas. They may want to relocate it if there are enough sightings in your area or they may warn people to stay away if they find there are cubs or something nearby. Good luck.
