Just a reminder for those of us who have pull ropes for our pop doors. I got a call from a friend tonight who lost his friendliest hen this morning. He went to open the pop door and when it was halfway up the pull rope snapped and the door came down on the hens neck. The hen was killed immediately due to a broken neck. So check those ropes for chaffing, UV damage, or just general wear and tear. Sometimes it's just the simplest of things...
