I have four chickens who are now 7 months old - a Swedish Flower Hen (Hilda), a Frizzled Easter Egger, a Silked White Easter Egger and a Plymouth Rock. I raised them from day old chicks. The only one that is aggressive is the Swedish Flower Hen. I have been more aggressive with her lately in response and she's responded somewhat. The Silked White is incredibly sweet and has just started laying eggs, even though I am not providing any artificial light. The Plymouth Rock will also let me pet her when she's getting treats and the Frizzled is friendly. I don't see any pointy hackle or saddle feathers on Hilda and she doesn't crow. She is the loudest chicken but it's not a crow. Can you tell from the photo if she is a cockerel? Thank you!!
