12 week old girls still have no color in combs

I have one Silver Sebright that is a year old and she still has a VERY small purplish comb and one Black Star hen that has a very pale comb. She is also a year old. I don't think it is a big deal. They all lay great and are very healthy.

 

My girls were born early February--they have not developed the red coloring either. Seems weird to me. Year old hen has a very bright red comb etc and is laying like crazy (EE). Nice to know they are developing just fine.

 

I have some from my NYD hatch that still haven't developed combs... Others are large and red but they haven't stopped laying.

 

Sounds like you are giving them everything they need. Some just don't get the real red red like others. You mentioned that you are in the desert and that may have something to do with it, but I doubt it is a very big deal. As long as they are healthy, laying at the right times, and acting normally, you shouldn't worry. Always watch for abnormal behavior (not seeming completely "with it," not moving as much, eating less, not laying if they had been laying, but not being broody either) but if they are acting okay, it isn't a big deal.

Edited to say: Also, mine didn't get RED combs until they finally started laying around 6 months old, until then, they were just pinkish. And with some of my barnyard mutts, they have hardly any combs to this day and they have been laying for 6 months.
