I have 6 amberlink chickens, they are currently 5 weeks old. My run and coop are ready to go, and frankly, I'm ready to get them out of my basement. Our temps are somewhere between 50-60 during the day, and mid 30s at night. They have been outside for a couple of hours every day that it's been nice enough for the last couple of weeks. These are my first chickens, so I'm new to all of this! Are they big enough to be outside full time in those temperatures? Thanks!
