I think the females have pea combs but l am not sure considering their age. The male has a single comb l think. I have attached few more pictures and specially of the male so the origin breeds can be acknowledged.Thanks for writing the comment.
Okay, so the girls both have single combs, which would make them cochin mixes.
The boy, it's still a bit hard to tell because he doesn't have all of his feathers. If you want, you could repost some pictures of him once his feathers grow in, but even then there is no guarantee that we will be able to tell you exactly what's in him.
