Five Buff O's and one Barred Rock, Hatched early Feburary and started laying early August. By early October they were laying 6 eggs a day. I became lazier and neglected to close the door to the coop, they roam during the day and go back in the coop to roost at dark. Went out to take roll one morning and was missing one buff. I speculate that a fox helped himself. Now I close the coop every night....no more losses. They have slowed way down on their feed, and I only get ONE egg a day. The barred rock is the only one I ever see on a nest.. Can chickens suffer from Post Traumatic Stress Syndrome....This one a day has been consistent for 3 weeks....Any suggestions ?
