When I got them they were yellow and one is really big there are 2 that are white feathered but the other 4 are getting brown on their feathers

Do you have some photos?
Other breeds of ducklings that are mostly yellow as babies are buffs and fawn and white runner duckling.
Your white ones are probably pekins. Would love to see some pictures

Yep looks like the brown ones are buff orpington ducks.
The white are most likely pekin.
Does that one with the crest on its head always stand that tall? Maybe its a runner duck
