I need some advice on my Cornish Cross. We got them in late August hoping to have them ready for processing before the cold weather hit. We were not so lucky. It has been below freezing twice this week. The chickens seem to be handling the weather just fine in their tractor but it seems to be having an affect on their weight gain. They are 7 weeks but are probably only about half maybe 3/4 the size they should be. I am going to weigh everyone this weekend to get a better idea of where we are exactly, but at this point I am afraid that even if I grow them out until the end of October (9 weeks), they may still be small. They are on a 22% meat bird feed. We have upped the amount we are feeding and they are actually leaving food in the feeder. We have thought about moving the tractor closer to the house so we can connect a heat lamp for at night, but wondered if anyone had any additional suggestions.
