Apparently Sylvester (who is an utter gentleman with me) is a leg-flogging dick with my chicken sitter.
Our quarantined in-house new juvenile is very comfortable with us walking around but as soon as a visitor stops by she is very wary that a stranger is in the house - unless they sit at the table with us and then she accepts them seeking treats from them or sitting on the bench next to them. Chickens like dogs or cats know who their humans are and a stranger puts them on alert.
I had no idea he would have an issue with my friends (who he's met when I'm home). My BiL, who grew up with chickens, is going to take over from my sister. I feel so bad (for the people and for Sylvester).
