I see what you're saying
@NORTHSH0RECOOP, Those are some pretty pointy feathers towards the top of you birds head and back of its neck. They look like newly developing hackle feathers to me. Hens neck feathers still have a point but are thicker and more rounded. From that picture your bird's look pretty thin. As of right now, I'd say you have two slow developing cockerels. Very pretty! And it's typical for young cockerels to be the slow feathering chicks, also, different breeds or crosses will grow at slower or faster rates. Keep us posted.
