So I have two hens that I got about 7 months ago. The smaller hen has grown her comb out and was laying eggs consistently (she's broody now). The bigger hen, however, still has not grow out her comb yet. I think she might have laid ONE single egg a month ago (there were two the very first day they started laying). I've read that a sign for egg laying is that the comb grows out. Is there any reason the bigger one still does not grow hers yet (and not laying eggs)? Thanks.
