I went to go feed my 8 week old chicks yesterday and heard what sounded like a dog barking in the coop. Let them out and looked in it is one of my roosters starting to learn to crow. He is making the weirdest sound. It's kind of a cross between a crow and a dog bark. All the other chickens stay away from him like "we don't know him" lol. They are so funny as they grow up.
