My Buff Orpington is 19 weeks old now, as are her coop-mates, a Silver-Laced Wyandotte, an Australorp, and a Rhode Island Red. The Silver-Laced has a beautiful rose comb, very bright red and a lovely waddle. The Australorp has a giant blazing red comb and waddle (if she had plumage on her rear, she would definitely be a roo!) and the RIR has the same, large and red, as is normal for the breed. But my Buff Orpington has a teeny pink comb and barely a waddle happening! She look like my other babies that are only 2 months old, except for that she is GIANT! Is it possible for a comb to be stunted? Is this normal for this breed? This is my first flock and I can't find any info for this issue! Any help I could get would be appreciated. She eats the same as the others, she is active and healthy, but that comb just isn't right!
