5 1/2 weeks old chicks

These two chicks are 1st clutch of 2010 season from H3N1 and H2N1 parents. By now, they are almost 6 weeks old and can eat/drink on their own. Actually around 3 to 4 weeks old, they begin to eat on their own thou they still beg for food from the parents if given the chance. Seems that the female has little darker color compare to normal female. The same parents produced at least one dark color female in last year which is the female H32N2 that I currently try to breed with H5N1 male.
