So today is their first day outside in their coop/runner. There are 4 silkies and their now 9 1/2 weeks old. I put a heat lamp in thier coop area and its on but theyre on the other side of the coop. The coop itself is 4ft x 3ft big. The runner is attached to it so its a walk in style runner which is 5ft by 7ft big. Their pretty much fully feathered but havent been outside at all. Ive had them outside now for about 4 hours.The temp. theyve had inside was about 70degrees and outside today its probably about 55 degrees so thats why I put a heat lamp out in their coop area for them. They are cuddled up right now on the opposite side of the coop not near the heat lamp at the moment though napping. My question is would they be okay to stay out there now permanently? Also their little door is open to wander around the actual runner area but they wont leave the coop at all. When will they start wandering around?
