Hi we have 3 x 8-10 week old chickens. The white One we think is a light Sussex. Is it a boy or a girl? And we have no idea what breed the other 2 are. The curly feathered one has started to ‘half’ crow in the morning and it’s tail looks roosterish? Can anyone help us out? The other black one is showing no signs of being a boy but we don’t know the breed. Thanks
