Twice now one of my chickens has been almost decapitated by this thing. I may still lose the hen that got badly injured last night. Haven't had a chance to look at her wound closely because my vicious rooster keeps attacking me when I go in (I'm getting ready to wring it's neck real soon). He was the other chicken who was almost decapitated. The Pullet Shut automatic chicken door really needs some kind of pressure sensitive safety or IR beam like a garage door instead of just a 10 second re-open setting. I've got it set to close when it's pretty much dark outside, but apparently they straggle every once in awhile. Anyone else have this happen?
