I hatched 11 peeps of my own and they're now a month old. I am seeing NO signs of developing combs. How can this be- all 11 pullets? I know, I know, they're too young to really tell, but I'm too impatient- I thought there may be some teeny tiny sign- like a bit pink or something, but I see nothing. Yet. All 11 could be girls? I can't believe my luck!
