Healthy dual purpose chickens. I have a feeder that never runs empty, They free range a couple hours every day for all the bugs they can eat. and their run is pretty large anyway! I give them treats of popcorn, kitchen scraps on occasion, peanuts sometimes, something everyday anyway! Ive been buying scratch grains for the last couple of weeks since it has gotten cooler outside, and throw a couple scoops to them closer to their bedtime and they eat till their crops look full! I have all 'dual purpose' breed chickens and too many roos that should be ready to be processed. But to me they seem to be thin. Is there something I should feed them to fatten them up? Are they just getting too much excersise? Lots of girls around to keep them busy and distracted from the food?
