Houston we have a problem

I didn't think we had a predator problem in the city. Boy was I wrong! I think this is a bobcat. At first, I thought it was a lynx. We found her when we heard our chicken screaming at three in the morning. </3 He carried our chicken over to the neighbors yard and ate her. My neighbor went out with a spray water bottle not realizing it wasn't a small domesticated cat. Parks and wildlife says she probably has a den nearby. We are not allowed to trap her to protect our flock. Parks and Wildlife says we have lots of Bobcats in town. Wow! Hundreds of thousands of people and bobcats living in the shallows. Now, how do you build a bobcat proof chicken coop?
