Hi all! We have 6 barred rock hens, a little over a year old. Today they are out free ranging (which they get to do about 4 days a week - when we are home). I noticed this morning, about an hour after I let them out, that one is missing. They always stay withing 15-20 feet of each other, and I have looked everywhere for this girl, but she is nowhere in sight. I also have looked for evidence of her demise (feathers, blood, etc) and have found none. Does anyone have any ideas as to what could have happened to her? Thanks in advance!
