I don't know what the lowest temp they can handle would be, but mine have been outside in the tractor since they were 3 weeks old, and we've gotten into the high 40's low 50's at night time, they've seemed to handle it well.
I plan on processing at 8-9 ish weeks, I'll go be weight, aiming for 8-10lbs live weight. I think the big variable in processing time lies in the feeding regiment you follow, I feed by weight twice a day, so my birds will take a little longer than someone that feeds free choice.
Thanks
I've heard that by 12 hr on and 12 hr off, or twice a day like you do, it is better in the long run with less health problems. I think they're going into the tractor at 3 weeks and worst case I'll use a heat lamp, but I'll bank on their size and number to keep them warm (I'll have a tarp over a portion of the run on 3 sides of one end of the run).
She was holding on at breakfast time, but barely. When I came out she was laying on her side and lethargic, her crop was still full from the night before, but she hadn't had any food. I fed the others and went to find a dropper to try and coax some liquids into her, but when I came back, maybe 30 minutes later, she was dead. She was still pink, not purple like I have heard happens with heart attacks. I'm thinking injury, or crop issues??
