Recently, we returned home (during the day....with hours of sun light left) to find our first and finest egg layer (RIR) dead in our chicken yard. The others were freaked out, hiding under things (or in the coop). The dead hen seemed to have the feathers ripped out from either side of the back of neck area. There appeared to not be any chewing. It seemed like her neck was broken and flopping, even though the rest of the body was intact and in rigor mortis. The only open wounds we found were a single laceration (about an inch long) in the area where feathers were ripped. We have had problems with racoons at night, by never during the day. If if was a dog, we aren't sure how it could have gotten into and out...it would have to scale a 5 foot wire fence (hard galvanized wire, not chicken wire). Could this be the work of a hawk? Since the attack, we've built a bomb proof chicken run, enclosed on ALL sides with hardware cloth. The remaining girls (6 of them) are safe, but not happy...they don't get to wander the yard. No one has laid an egg since the attack. Do they stop laying if they are stressed? Many thanks, C.
