Hi All. I'm hoping someone might have experienced this and have some insight. I have a hen (about 18 months old) in my flock who has recently started regularly making false alarm calls (the shriek used for foxes). The whole flock is then getting set off and I'm having to keep running up there in a fright thinking they've been set upon. The real downside though is that the flock is starting to become complacent about the alarm because she's doing it so often. That's not good because there are foxes around. She isn't being attacked by any other chickens when she calls - she's always off on her own. It almost seems as though she's going mad. Today when she called she actually ran away as if there was really a fox there chasing her, but there was nothing. She seems otherwise pretty well, though she has recently been looking a bit dishevelled. I figured it was moulting, but it's much worse than the other hens so maybe something more is up. Any clues?
