I have 3 pullets and one cockerel. the cockerel has started crowing,and actually acting like an actual rooster,which is weird because he is so small still. The pullets are very normal,accept for the gold one,she isn't afraid to get a little aggressive with the other bigger hens at times either,and the black cochin pullet will do the same.The golden one has a very small reddish comb and waddles. Their all around the 3 1/2 and 4 month mark,but still seem very small.Im sure they'll grow. Any idea when they will start.
