I gave an EE rooster to my mom about a month ago and he has been doing great but today I go over and see that his neck is looking like all down feathers or something? It just looks fluffy and grey where before they were red and obviously his normal pointed hackle feathers. He seems completely fine otherwise and so are all of the hens. Just curious if this is something to worry about or what caused it. He is almost 2 years old. I'll add a pic of him today and an older one of how he normally looks.
