We got this chick at our local feed store a long with the sex still unknown EE. I thought at first she was a RIR. But I'm not so sure now and I'm questioning whether or not its even a she. The store said she was a pullet. My RIR hen I have was just so much different all around at this age and this ones coloring is not as brilliant red. She is also very aggressive and this morning I seen her do something I've only seen roos do. While my EE cowered, she stood tall and then flared her neck feathers up. She guards my EE but will bump/charge at it too. At 6 weeks I'm already seeing small red wattles but my RIR had them and a red comb at this age too. Any idea of her breed and sex?
