Hi im new to chickens in general and these 4 chick's where given to me with their parents. Both parents are splash silkies. out of the 4, one is a very light grey and is now developing dark feathers were their other siblings are white and starting to get their splash colours. How come their like not like their sibling? I'm excited to see hoe they turn out and I'm dying to know if they will be a different colour?
