I have a Light Brahma approx 7 months old who acts like she is going broody - sits on whatever eggs are in the nest - for as long as 18-24 hours then it's over and she is completely back to b eing herself. She has always been a "special"** chicken but she has done this three times in the last few weeks. Is she practicing? Has anyone else's chicken(s) done this? What's up? I don't have a roo, but just wondering if it could be hormones or what. **Special as in she doesn't always play well with the others, doesn't like to share food, doesn't want any of the other girls on my lap except her, is always the last one in the coop and squawks about it every night.
