Question would feeding them corn help fatten them up a little faster? Yes the not letting them have a ton of roaming area makes sence too, I have found Barred Rocks are more of a light weight boney chicken, even the roosters although the look huge and beautiful that is really all they are is looks. Still when you have too many roosters that is the best option. The trading idea is a good one. Not sure how that would fly (pun not intended) lol for around my area most people don't have the nerve to cull them or send to slaughter.
