We got this hen over a month ago and after the pecking order was established with our existing girls she started crowing in the mornings like a rooster for over a week getting louder and louder. She stopped crowing yesterday and didn't crow this morning. I've been doing a lot of online research as I heard it could be common for a hen to crow but I think she's a rooster, not a hen after all. She does not have spurs, but she does have saddle and tail feathers like that of a rooster. Here's a pic - thoughts?
