I have a NH broody hen who has hatched at least 3 chicks so far and is still sitting tight. Yesterday I noticed that she had a very small comb compared to all the other hens. My question(s) is: is this a characteristic of a broody? (having a smaller comb from more estrogen)/ or could it be from a result of not eating much for the last three weeks?(depletion of fatty reserves)/ or could this just be the way she has always been? Could those of you who have broody hens do a check just to see and compare? I will take a picture and compare it to another pic I take in about 6 to 8 weeks to see if it gets larger just to rule out option # 2.
