Hello! I have 3 golden comets that are now 6 weeks old. They are currently living in the brooder in our garage but have not had any supplemental heat for the past 2 weeks. Today it is 68 fahrenheit outside right now, so would it be warm enough to let my chicks go outside and into the coop for a few hours? They will still sleep in the brooder at night, but I wanted to let them outside for a bit. We have a safe and secure coop that is already built and ready for them, I'm just not sure if they're too young too go outside. Thanks.
