My flock has always been pretty laid back, nothing bothers them. For the last week or so they've become a bunch of nervous nellies. They stick to the woods pretty much all day. They still come running if they think I have treats, but let me move ever so slightly and they all scatter. It's bothering me. DH says it's just the weather or change in barometric pressure or whatever. I'm wondering if they didn't have a predator scare that I don't know about. Anyone ever experience a sudden change in temperment of their flock? They are 14 LF brahma - a roo and 13 hens. They will be 2 years old in April. They free range all day.
