My little Goldie has been broody for almost 3 weeks. She rarely comes out of the nest when I open the coop door for free ranging, but when she does she flies at me or runs at me like she is trying to chase me away. This is my girl. She has always been sweet, friendly and docile. I don't understand. She has gotten so skinny, so I have been giving her food and water in her nest because I'm so worried about her but now it's like she has turned agressive toward me. Why would she behave this way?
