Simple, she has been on beakbook as
@Ponypoor suggested. I am afraid though she did not pick those words up from her flock. Momma hen is on there lecturing all the young hens and pullets. She is offering 2 online seminars. The first is "Going Broody. It is every hens duty." The 2nd is "Releasing Your Inner Demon. New and Inventive words to curse your human slave."
Tassels has obviously completed both online courses and Momma Hen is proud of her student. I however apologize. Many of Momma Hens new and inventive swear words she has picked up from me over the years. I have called her everything under the sun while she has been broody. She took notes.
