Most of what you are showing looks to be japanese. However, the blue one without feathered feet is a self blue oegb. The one with feathered feet is a porcelain d'uccle, I think All the others look to be japanese...you might have a few more oegb's in there. It's hard to tell them apart sometimes The blue one with feathers might be another d'uccle....although, it doesn't have poofy cheeks....hhhmmmm....
The spotted one is a mystery to me...I've never seen one marked like that...maybe a modern game???
I can't wait to see pics as they grow...keep us updated
