I have 2 auracana and 4 barred rock that are now 4 weeks old. I would like to move them out to the outside coop. I use an Eco Glow heater in the box inside. I live in New Hampshire. They would be put outside into a tractor style coop and yard fenced in. I could put the eco glow into the outside coop for a while for cooler nights. What do you folks think? Are they still too young to go outside? Pictured is the Eco Glow. Not a current picture. This is when they were like 2 days old.
