buff bantam cochin chicks dropping like flies.....help

[jack & mommy's duckies]

I got a few buff bantam cochin and other coloured cochin chicks from a breeder. 3 times now the buff make it about a week sometimes two and grow no feathers and die. I also tried hatching some of the eggs out myself to see if they were carring something and same thing happened. And it just seems to be the buff. the black, blues, splash, barred and frizzle ones are all good.

Any ideas???? Is it got something to do from the breeding??? I'm looking for any ideas at all.

Things I tried:
- keeping them warmer then the other chicks
- vitamin B in the water
- leaving them in the incubator longer
other then that I have no idea.

At this point the last 2 are about an hour from dieing........but there are a few more eggs in the bator so what else should i do???
