Well it's a story about my friend's house chickens. At one time she had 3 bantam pullets and a bantam special needs rooster. My friend, otherwise lives alone. When I visit her, all the birds disappear, they hide behind the couch.
I sit on couch and can watch what they are doing but, they think they are invisible.
They keep checking around the corner to see if I have left yet. The longer I stay the more frequently they check.
My friend says they also do that when any repair man comes over. In fact the tv guy was so awe stricken after seeing them peek out. He took photos with his phone, so his wife would believe him.
