I am new to raising chickens. 15 weeks ago we got 4 pullets of different breeds but I am confused by one in particular. It is supposed to be a leghorn but each of my other chicks started getting a comb several weeks ago but the leghorn has no comb that I can see. Is it some genetic defect? Or do the combs develop later than other breads? Is it a different bread that somehow got mixed up? Is it a rose comb that is just flatter than I am expecting? I sure hope it is not that my others are all cockerals and none should have combs at this point. Let me know what you think. Sorry for the poor lighting/flash in the picture. Also are the furry feathers on cheeks normal?
