My flock free-ranges, and for the past 3 days, Emmy the Phoenix hen has been disappearing for most of the day including at night - she doesn't go into the coop to roost with everyone else. I thought she had been taken by a predator, but my husband saw her outside the coop yesterday afternoon, so I know she's still around, but she was gone again by the time I got home from work. Could she be broody in the woods somewhere? If so, should I be worried that she was off the nest for about at least half an hour yesterday?
