I have 3 hens whom are 7 months old, free range, put themselves to bed at night and are great layers. A couple weeks ago I had one Rhode Is. red go missing. I figured it was picked off by some other animal as we do live in the woods and we searched our property high and low for her. After about 7-10 days she magically appeared out of no where! Which was great! But the same day, disappeared again? My other hens will literally follow you around the yard if you are outside and are begging for food any chance they can. So I am very confused as to where my other hen could be? Any suggestions?
