So I have a black sex link who recently started laying. She has laid 11 eggs so far. She spends most of her day in my backyard and in a coop at night. When she is about to lay an egg she comes and stands at my door to let me know she is ready and usually caws for a little while too. She usually arrives an hour in advance. Once she lays an egg I store it away, so I can collect the entire batch and then let her sit on it. However as of late her behaviour is confusing me so much. She is cawing louder than ever and making different sounds too. She stands near my door but when I bring her in to lay an egg, she just screams even louder. So I let her out, but then she comes back and stands at my door and I bring her in and she does the same thing. This happen 2-3 times.I heard hens get broody before they are ready to sit on their eggs. But because this is my first time hatching eggs, I have no idea what exactly a hen does when she gets broody. All I know is she nestles up and sits there for a while and is hard to remove. Can anyone tell me what my hen is doing? Is she getting broody? And what are the symptoms of a hen getting broody?? Thank you.
