My 7 pullets are now right around 20 weeks old and they still have little combs and wattles and are still very pink. Their faces have not turned red either. Is it just a matter of time so could something be wrong with them that I should be dealing with? They are a mixed flock of White Leghorn, Black Australorp, Salmon Favarolle, Welsummer, Black copper Maran, and a Mutt (one of each). The reason I think it might not be justy a matter of time is that they have been very lightly sneezing for the past month and a half. They are still eating and drinking well and if not for the occassional sneeze they seem healthy. When I first started to hear them sneeze I treated them with duramyclin-10 but it didn'e seem to make any difference.
