Hi, I live in Los Angeles (so no frostbite risk) and I noticed that one of my rhode island reds has some dark purple on her comb. The problem is that I don't know if she had this darkness before or not. I don't think so but not sure. She's eating and hanging out fairly normal. The only difference in behavior is that she the last week or so she has been sitting a lot like she laying. They were dewormed about six weeks ago. Should I be concerned? Any input would be appreciated.
