Hi my buff orpingtons comb is dark purple, her waddle and cheeks are the regular color red. Her comb changed to this color about 2 days ago. Is there anything wrong with her?
Waddle Is Purple
The color probably means the comb isn't getting enough oxygen, which could have several causes. We'd need more information to make a decent guess. You could answer these questions: http://www.backyardchickens.com/t/3569/have-an-emergency-disease-please-read-first
Also tell us whether you've checked for mites / lice, whether she's been wormed, and with what.
