I am going to pick up 4 replacement hens today from a friend who is downsizing her flock. I have read about the "right" way to introduce new hens, but I think this situation is a bit different. Our existing flock is down to one hen, after a predator attack a few weeks ago. This one hens seems to be healthy and doing well and laying again. But I suspect that one hen does not constitute enough of a flock to need to go through the usual slow introduction method. If anything perhaps I need to intro the old hen to the group of 4 new ones? I was planning on putting all the hens, new and old, into the coop and locking the door this evening and leaving them inside for at least 24-36 hours. Possibly longer as there is supposed to be a 2' snow headed this way so perhaps they will be inside for 3 or more days. I'll check on them daily, but don't think there will be time to let them out before the storm. Hopefully this will be enough time for the new ones to "get" that this coop is now home and know to come back inside after they finally go out. I've never added new birds before, and was just wondering if this plan seems OK.
