I was just outside with my 2 girls (I never let them free range when I'm not there) and turned around to see a fox clear the 6 foot fence. The girls scrambled and a screeched, I wasn't expecting a fox, and it jumped back over the fence. I scooped up the girls and put them back in the coop, where they voiced their displeasure and then went upstairs to the nests. What do I do to ensure their safety? We're in a neighborhood setting, but have had foxes because of the parks in the neighborhood. Is there a deterrent for foxes? So far I think they're safe in the coop, but a determined animal could get in I'm sure.
