I just got in a batch of 25 Cornish crosses for a broiler show I am doing for my agriculture class. I have only had them for a week, and they are all growing noticeably bigger, except one. One is about 1/3 the size of the others and still has no feathers growing in on the wings when all the others do. The small one, I've named him Freddy, also has blackish grey on his feet and around his head. Its very faint, like someone used a paint brush and brushed ashes on him. Did they accidentally give me one that is a different breed? Or is he just a late bloomer with funny feathers? I'm secretly hoping he is a different breed because he is the friendliest out of all of them and now I'm super attached! I'm trying to post a picture of him, but I'm new and can't figure out how!
