We entered our pen this weekend and found one hen dead and completely ripped open on her back and partially eaten. Another one torn open but still alive and not eaten. Both were under their coop (which sits 3 ft high) in the corner of the pen furthest from the gate. We can't figure out what got to them, but all the others save for one who had flown OUT of the pen, were hiding in the coop during the day and looking frazzled. We cannot figure out what got to them, but the only way would be througha hole about 3 inches wide in ur garage that leads to the pen or a tree and roof of our garage overhead. Anyways, since then the rooster's comb and wattles are very very pale and he is not himself. He has no wounds but doesn't apporach and try to puff up like normal when we come to feed him. He usually is very territorial, but stays back on his own instead of inspecting what we are doing. Any ideas?
