Well.. One thing led to another and I ended up raising a young bird, alongside a motherly dog and a cat.. A year later, I have an awesome little buddy. But she doesn't "cluck". Her usual sounds are soft little squeaks.. She will "caw" like a crow when she is irritated. And "coo" sweetly when she is cuddled. But no "cluck". Is Chicken vocabulary a learned thing? .. Chicken Nuggets is a member of an interspecies flock. On that note, I have seen her imitate the dog and cat. It is hilarious! This picture, for example.. The cat likes to have naps on this bench in the sunroom, laying on her back.. Now the hen does it, too. They also taught her to bang on the glass door to be let in or out.
