I noticed yesterday that one of the 5 week old chicks has a different comb than the others. The largest of them has rounded & fewer bumps while the others have more bumps and they're more pointy. The chicks are only 4 weeks old now I guess. They still have some of the down type feathers but the barred feathers are coming in good. Most of them have some reddish or pinkish in their combs too. Is that any indication of the sex of the chicks...whether their comb has rounded or pointed bumps?
