Has this happened to anyone else? My 5 Welsh Harlequin females, 3 1/2 to 4 months old, are very suddenly acting afraid of me and everything else. They've been super-calm and friendly; they have never wanted to be touched or picked up, but are very used to me, easy to herd in at night, not upset by the chicken coop being constructed near them, etc. - really, amazingly calm! Then, yesterday morning they didn't want to come out of their coop/run area; panic and run into the corners if I come in; don't want to swim in their pool (which is totally unheard of!!) or go in the garden; & leap into the air like they're trying to fly away, if I open a bag of feed or move at all quickly. Normally, in the morning, they're running in circles next to the run door as I open it, and file past me talking happily- then they spend the whole day out in the garden. They'll come and hang out with me when I'm weeding or sitting in the garden, too. 3 have eaten out of my hand, and would come when I called. This change in behavior is very sad to see, and all I can think of is that something really scared them night before last. We don't have many people nearby, so I don't think a person did it, but it could have been a predator outside the coop/run door. Gosh, all my poultry have psychological problems! My neurotic geese have settled in, though, and I just hope the duckies do too. Any advice, other than to just be calm and slow-moving around them?
