Hi! This weekend I plan to integrate NINE 6-week old chicks into a coop/pen situation with TWO existing 11-week old pullets. One older pullet (blue-laced wyandotte) is super docile. The other older pullet (cinnamon queen) is about average in temperament (smart and curious, but not aggressive.) Since they are all still "chicks," and since the young ones far outnumber the older ones, can I put them in together right away? I am really hoping to avoid having to separate them at night, as I only have one predator proof coop outside. Please let me know what your experience has been. Thank you!
