So possibly a dumb question! Comb sizes on chickens... do they mean anything (like indicate age or anything else?) or is it just cosmetic? I was just given two more chickens. The one in the back is LITTLE... an itty bitty little chicken (she probably weighs 3lbs or less) but she has a giant floppy comb- way bigger than any of the other chickens (it almost covers her eye on the side it lays down on- you can't see it in the picture).
