My RIR comb is falling over!!

[chick_magnet]

Ok i bought some RIRs and some of the cockerels' comb are falling over. At first I thought it might be pullets but read somewhere that cockerels feathers are bright with a glow and i now can see that. Only some of my cockerels' comb are falliing over. what does that mean? Also its not really important but when would they start to crow? they are almost 3 months old

Long ago, I had RIR and some had combs that fell to one side. Since the comb was a healthy red color and not splotchy I didn't worry.
