Hi. My roo is a Columbian Wyandotte roo and one of the breeds of hens I have is Partridge Rock. I have some dark brown chicks that hatched (which would be the partridge rock mixes). Right now they are only a week old. Any ideas on what they might feather out to look like ... I am pretty sure they will have the rose combs. They are starting to get a few little feathers at the edge of their wings. Please don't tell me I am getting mutts because I know they are mixed breeds.
