I have a Chicken Tractor I like to use to raise cornish. I've never gotten them before April. I did a batch last year but it was HOT out, so at 2 weeks they did just fine outside in the tractor 24/7. I am SO TEMPTED to buy a few now from TSC, but I don't want to raise them inside. They're too dirty and stinky. Any thoughts on this? When could they feasibly do decent outside on pasture in the tractor? By 5 weeks they're GIANTS! I'm in upstate NY. Temps at night are still freezing. Daytime - 30-40 norms.
