A week ago I noticed the buff silkie's comb start changing. It has thickened up and looks raised and lumpy and pink. Does this look like it's going to be a rooster? The blue silkie is from the same hatch but has always been smaller and the comb does not seem to be changing much. We live in a residential neighborhood so no roosters allowed. The farm store we got them from will gladly take roosters back though. We are of course getting attached as these are family pets. Any ideas? Thanks!
