Chocolate and Chocolate Agouti Color Development

When Chocolate and Chocolate Agouti are born, they look very much alike at 3 days old.   The top one is the chocolate agouti and the bottom is the self chocolate.   The little light colored ear gives away the information of an agouti gene.

Agouti gene has the orange/tan undertone, so the color gets lighter when the wool starts to grow at 2 weeks old.

The same two bunnies now have some wool at 8 weeks old, both have lighter wool than at birth but the self chocolate retains darker color face and body wool.
