First off I am new to all of this. I recently got into raising chickens. I have what I believe to be 4 females. 1 though is in question. I have 1 Ameraucana that started crowing in the morning 2 weeks ago. Not every morning either, just every now and then. They are only 10wks old now and from what I was told they don't start crowing until 4-5 months of age. I have had a few people tell me to check for a bump on their chest, which she\\he does have, then it's a female. I also read to check for pointy feathers on the back before the tail feathers. This chickens feathers are rounded which I was told means female also. I haven't heard the crowing for a few days until today so it's got me worried again. This chicken is also my shyest one. It's the white one. I can take better pictures if needed.
