Get a baby monitor wireless camera - they are cheap!!! Put the camera in the coop and put the monitor by your bed. Turn volume down low but audible. When something bothers geese... YOU WILL HEAR COMOTION! Get gun - run! We have camera and can hear/check chickens on one channel and goose barn on other channel. . It is awesome! If you are having predators - predator proof your coops and then put cameras in or out and turn monitor on low on your bedside table --- it's a baby monitor... but it works GREAT to hear if somehting is happening! You can save your geese/chickens from horrible death. SUMMER makes one - all over internet. We got the 2 channel 2 camera one - just plug in, (extension chord if you don't have elect. to coop) and then put batteries in monitor and put by bed. We can see what they are doing if we need, hear comotion or problems and overall it's good security - we can even hear neighbors talking on it!! LOL!!!
