Well Stella only laid one egg and decided it wan't any good. She pushed it out of the nest. Bell and Dusty have two little pink chicks and one egg. Annie and Billy have four chicks. 
I'm going to take a stab at their color mutations.
#1 Dominant pied, violet
#2 Cinnamon, yellow face
#3 Dominant pied, yellow face
#4 Normal, yellow face

Looks like their will be some pretty nice color.
