Exotica, Love the idea of the disco ball! Looks way better than a bunch of cd's. You might want to start a disco ball thread in this forum to share that device with others! We have plenty of Red Tailed Hawk in our (yours and mine) area also. That's what swooped on mine, but a cooper could easily snatch and fly off w/ a lil silkie. I do see other birds chasing them and know that crows are a deterrent, but I sure don't want a bunch of crows screaming around here! IMO, I wouldn't start up feeding the wild birds again as they do carry so many diseases. I saw pics of your yard and you do have quite a bit of cover, so you're babies aren't like sitting ducks. I hung a couple silver metallic kid's cheerleader pom-poms from the 99 cent store to run the birds away from my coop. Hope you have a great weekend to enjoy this glorious weather and your lil chickens.
