Hi, My chickens are about 18 weeks old now, and one of them, a red star has suddenly become very aggressive with me, pecking at my clothes and giving me the hairy side eye! She's come at me and I shoo her away but today she jumped up and pushed her chest out like she want to rumble! I've heard no attempts at crowing but I'm not sure at what age they show definite signs of being a rooster. They are in a coop in the evening and night and out mostly all day, she does this much more inside the coop, but still has her eye on me when they are outside. I've had chickens for 9 years with the last 6 months chicken free while we built a Fort Knox coop to keep out the racoon, never had this before. I'm not sure what to do this, little chicken has me running scared!!! Any suggestions?
