I have 5 chickens and 1 rooster in my original flock and got three more chickens to fill my coop to help keep everyone one warm this winter. I live in Maine and have a feeling it’s going to be a cold one this year. My quarantine period is over and I have divided my run and have all the chickens in the run during the day. They can see each other and spend the day together. How long should I continue to do this before I put them together? I was thinking two weeks but it’s startIng to get below freezing at night and I am worried that the three girls sleeping in my large, wuninsulated, garden shed will get too cold. Plus my shed is not ventilated very well and can get damp (I really need to fix that). They are in a large dog kennel with a roost and I cover them with blankets at night. All of my birds were born in July so they are all roughly the same age and size. Any advice is appreciated.
