Chanteclair Chicks Hatching

The Chanteclair eggs started hatching on July 25th and continued on the 26th. As I upload this video 5 of the original 8 eggs have hatched and the little bantam is still sitting on a couple of eggs. I will remove the remaining eggs on the 27th if they haven't hatched. I'm curious as to why there are two colours of chicks 2 are a definite yellow and three are a very light yellow almost white. It will be interesting to see if this is an indication of gender.
