My Campbells are three and a half weeks old. Getting some feathers but not all feathered out yet. I have created a play yard for them outside that is secure and safe from predators...for day time fun. The last few days have been in the upper 70s and they have really enjoyed the new freedom of being outside. As I type this the sun is going down and it is about 65 degrees in the shade where they are. They are all snuggled up together quietly napping and I will bring them in soon...but is 65 too cold for them? What outside daytime temps are too cold at this age? We are set to have a cooler weekend and I do not want to create any unnecessary problems for my new little babies!
