is my she becoming a he?

[Xtineart]

I'd noticed my dominant hen has been behaving like a right stroppy cow for a while now, and had been treating her feet for what I thought might be leg mites as her legs had gotten noticeably thicker than the other girls, one thing that does seem odd is the fact that she is developing quite prominent spurs. She is still my best layer popping out a perfect egg everyday but I'm wondering if this is a sign of her going through the change. Should I be concerned?

Some hens will develop spurs, so if she's laying eggs, she's definitely a female. Older, dominant hens in particular seem to develop spurs.

ok, she is older than the other two by about a year and the dominant one so glad it seems nothing to worry about. still going to keep an eye on her as she's really out of sorts lately and not even making proper chickeny noises, she sits and whoooooo whoooo's like a owl. strange bird.
