That's funny! I used to have that exact conversation with my daughter when she started her baby babble!I like to have "conversations" with all of my pets, cats and dog included.
For the chickens though, most of mine are still young enough that they make little cheepy sounds, especially a Whiting True Green named Toast that is 2.5 months. She chirps very lightly but constantly when she hops in my lap and sits down for pets. I like to think she's telling me a story, so our conversation is something like "Hi, Toast!" *cheep cheep cheep* "Oh, goodness. Tell me about it!" *cheep cheep cheep* "Oh, really?" *cheep cheep* "Well, what happened after that?" *cheep cheep cheep cheep* "Uh huh, what did you think about that?" *cheep cheep cheep* "Oh wow, and what did you do next?" *cheep cheep cheep*
My oldest girls just hit 3 months and the most mature one (so far) sounds like a honking goose right now, so those conversations are also fun because I can't take her seriously.
