I usually let my girls out of their run to forage in the daytime when I can keep an eye on them. Normally, when it gets to dusk, they return to the run and into their coop for the night. I only do this when the weather is good and if I am at home to watch the sky for hawks. Otherwise, they have their big covered/protected run to romp in. So here's the thing: a couple of weeks ago, after our snow, I let the girls out and they enjoyed their day, but four of them must of got snow blind, or just plain disoriented and didn't return on their own. I found them after dark as I walked to my studio. They were wandering aimlessly andwere lethargic from the cold, so I picked them up and put them in the run. Didn't let the flock out of the run for several days until most the snow melted. But, once again, two of them didn't find their way in for the evening. So I put them in myself. Interestingly enough, they weren't the same ones that had done that before. So, no out-of-run foraging time until today, no snow on the ground, temp nice, perfect. All come out, enjoy their day, then I go out at night to close the run, and what do I see? My black australorp sitting in the middle of the yard. If it wasn't for my having turned on the porch light, I wouldn't have seen her silhouette there. So what is this new behaviour all about? No snow, so that's out. It was never the same ones, so I can't say its one or two renegades. The weather was good. They're fed, watered, heated coop, spoiled, clean nests, laying everyday.... I just don't know what to make of this new, apparently random, behavior, but I am hoping some of you more experienced folks might have some suggestions, ideas?
