My cornish xs are 2 weeks old today and I booted them out of the garage about 4 hours ago. I just finished my pvc tractor with half covered with a tarp and one corner has a small piece of tarp on it. I hope they will be ok. Not a good first night out. They have never been in the dark either. The kids want to bring them back in the garage, but I keep telling them that they will be fine. I hope so! Its been mid 80s for highs and upper 60s to low 70s for the lows.
