I am totally guessing based off images I have seen.
I think pictures 3 and 5 are Saxony.
Picture 6 a harlebell
Pictures 8 and 12 golden cascades
Really, I think you will have to wait until they get a bit older and the body style changes or feathers start to come in. We will be in the same boat soon. We ordered saxony, silver appleyard, and welsh which the ducklings look similar. Have fun with your new additions and Congrats!
