The chicks are obviously dyed PINK.Its hard for me to see pic good enough to know what's going on.
As for "lavender orpington chicks" I've hatch many in the past and no they look nothing like those.
Have a feeling what you're thinking of as a lavender chick is the same as me.
Here is a pic of a lavender leghorn I hatched couple days ago.
Lavender in front. Chick in back is blue.
