I have two 9 week old chicks that are Polish/Silkie frizzles. They have been inside up until a few days ago. The weather has been beautiful. In the seventies and eighties, and about 50 at night. They have a coop and run, and they are in the back of the coop, in the build-in nest box with lots of grass hay. Their coop door is open at all times. There is a window, but it is near the top of the coop, and there is no draft from that. The weather changed suddenly, and it's going to get down to 34 tonight! I don't know what to do. Will they be too cold? Should I bring them in?
