Do all roos have green iridesence or do hens have it in their feathers also? I've 24 EE's and I'm noticing some changes in feathers...one is even turning black headed from brown headed??? They will be 19 weeks old on Friday! I'm also counting my chickens with the pointed hackle feathers (the feathers around the neck) and many of them have pointed feathers around the neck. Since no one is really crowing yet...I'm starting to get confused who's roo and who's hen? Maybe I'll post some pictures! I've also noticed their combs are changing which I know starts around laying time. BUT everyone here made such a big deal about THE redder...the rooster??? Any ideas?
