I have a small flock of mostly 18 week old Barred Rock chickens. I know the gender of 6 of them but 1 is causing me to scratch my head. He/she is smaller than the roosters with a smaller comb and wattle and is lighter in color than the hens. He/she doesn't get involved when the roosters try to show each other who the boss is, but his color is throwing me. I'm leaning toward hen, but wanted someone else's opinion since I'm new at this. Thanks!
