I was just wondering how many people check on the birds at dark. I have an automatic door opener on my coop. I had introduced 4 new hens to the flock and for several days the older hens wouldn't let the new birds in the coop at night. The door would close and they would be locked outside. I would have to take them and place them in to the coop. After about a week they're being in with the others at dark I quit checking them. The first morning after we had single digit night time temperatures I found our smallest buff orpington lying dead under the ramp to the door. Since then I've been back to checking each night. Tonight I conducted "bed check" and found I was short four. Checked outside and found them huddled on the outside roost. It's cold, windy, and damp here and low nighttime temps are predicted. Had I not checked I think I may have lost a few more birds. So while automatic doors are nice, they still don't replace physically insuring that your birds are safe for the night.
