I am quite frustrated with my feathered children at the moment. It seems that every week there is something unusual going on with one of them. A couple weeks ago we left home after dark to go to dinner. As I was driving out of the yard the headlights shown on the tractor and I caught a glimpse of a Buff Orpington sleeping in the run. We put her back on the roost with the other chickens. A few days later she did not come home at dusk like the others, and dh found her roosting on the grill at the north side of the house. He put her in the coop and all was well. Yesterday we noticed that she was missing several hours before dusk, which is not entirely unheard of for several of the hens to do from time to time.. so we did not worry, but when she did not come home at dusk we searched unsuccessfully for her. I suspected a predator may have gotten her or would get her if she stayed out all night, but this morning when I went out to do the usual checks and let everyone out, there she was, walking around the outside of the tractor like nothing happened the night before...What the heck? Why is she doing that, and what should I do if she continues?
