I'm really feeling like the worst chicken mama in the world. My coop and run are right outside my kitchen door and every time we get a really beautiful day out, I throw some scratch right out the door and let the flock stretch out and get some free time. Whenever the sun starts going down they go back inside the run. When I lock up, I count heads. Never had a problem until last night. I counted and came up way short. I spent the next two hours with a flashlight looking all over my property. I found 1 hen under the baby's stroller right by the back door. But no one else. No feathers, no commotion. This morning my neighbor that lives about 5 houses away (which is pretty far) brought home my paint roo. 6 are still missing. 4 of which are hens. And 2 are the young D'Uccles. I'm so mad at myself. Has anyone ever had chickens disappear and then come home?? I'm putting the baby down for a nap and then I'm going to search the woods.
