Are these mixes instead of Cream Legbars?

I hatched these Cream Legbar chicks from a breeder. They are supposed to be 100% legbar from the Jill Rees and GFF 2013-14 lines. However, three of the five that hatched are very light and don’t have as much of a down “crest” as the two darker chicks. They aren’t recessive white- they have darker wing feathers. I asked the breeder and they said that the Jill Rees line throws light chicks. However, I’ve researched and haven’t seen pictures as light as these. Does anyone have any input? 2/3 light chicks hatched from green eggs (consistent with Jill Rees). The other hatched from a blue egg. Thank you!
