Lost the leader of my flock to a coyote a few weeks ago. The remaining three girls were spooked for a day or so but then went back to their normal (and carefully supervised) free-ranging behavior. Then they had to deal with the disruption of being boarded for two days as we had to be out of our house for a fumigation. My broody Silkie came back un-broody after the boarding, so it wasn't all bad. Their behavior was normal for a few days but yesterday morning and this morning, none of the three will come out of the coop even to go into their pen. Yesterday I thought maybe they had seen a predator and were afraid, but they don't seem afraid this morning, just sitting on their roosting bars in the coop and declining to come out. All seem healthy. Any ideas as to what's up with the little agoraphobics?
