Hi! We noticed one of our hens has some weird light coloring around both her ears. She’s about 5 months old. It’s been very cold here lately. Could this be frostbite? I’m new to chicken keeping so I’m not sure. Could it just be her breed? I didn’t notice them like this before but I could have just not noticed until now. All my other chickens seem normal and besides the coloring she’s acting fine. Any suggestions would be appreciated. Thank you.
