So I get up this am and go on the back porch to hear our lil roo greet me good morning and look up at the porch, and they were quiet & hiding behind the door where I could not see them. So I go down & place them one by one in the run like I do every morning & our silkie hen was just standing there all close to the ground making a very soft noise, and NOT moving. I go towards her talking to her & she does NOT move. I then look around and the other 3 are doing standing like statues...no one is moving. Poor Polly put her head in a corner & stood very still, my roo stood in the middle of the run and was silent & still and my smallest cochin hen stood a foot away. Both faced the same direction and the silkie was looking down thru the woods & would NOT move.....Strange?? I was talking to my husband and still NO movement...and to top the weirdness I had just dropped a pan on oats in the run! I went back in the house & a bit later looked out & they were fine, but it was sooo strange! Do they sense danger?
