Hello, I'm new to backyard chickens and to owning chickens! My husband and I have five 2 week old chicks. They are already starting to grow feathers on their wings and are very active in the indoor set up that we currently have. I wanted to know at what time we can keep start keeping them outside permanently. We live in the Sacramento Valley of CA where temperatures are 80s-90s during the day and a low of 50-55 at night. Also, we are open to any other suggestions you may have regarding this topic. Thank you in advance for helping a newbie!
