Maybe the first alien family observed you, felt you were normal and copied your actions. Ok they had a dog but lots of humans do. But then they had to watch carefully because you had something unknown to them. They gathered from watching you that chickens...
Lol. I am really enjoying reading about your experiences. Nice to know I'm not alone. I guess we're all the crazy chicken people!
Maybe they were worried the chickens would eat their illegal plants. Lol
