Hi there, I have 5 week chicks just spending their second night in the coop and doing great! I have a couple of questions about when I can open their pop door for the first time plus what to do after that!? I've heard to let them spend time getting acquainted with their new home before allowing access to outside during the day (they will free range...we have plenty of yard/land). How long do they need to only stay inside before I can open the door? Also, once they do find their way outside, is it easy to get them back in....will I have to wait for them to do it themselves at night!? Should I be vigilant the entire time!? I can easily keep an eye on them for an afternoon, but not sure about chick-sitting sunrise to sunset! So, that's the basics of my questions...when and then what!? Any other helpful suggestions or advice are surely welcome! Also, I live in Montana and the days are mid-70s, evenings cool at low 50s. Thank you!
