We had a coop built and it is being delivered today. We are in Charlotte, NC, and the weather is mild during the day. Still chilly at night. Would it be ok for my chicks to be in their coop during the day and brought back in at night? They are getting crowded in the Tupperware container I have them in now. The coop has an indoor area for roosting and nesting. There is an upper outdoor area (covered in chicken wire, of course), and a lower outdoor area (also enclosed) where they can scratch and eat bugs and grass. Also, should the coop be placed in a sunny area or does it matter? I have a particular spot in mind. It is a quiet corner of our yard but very shady. Thanks.
