So I picked up 12 new chickens today from a local person who was getting rid of her flock. I talked with her for a long time and she takes really good care of her chickens so I don't think I'll have a problem, but I'm new and wanted to check. I got 11 various hens and 1 buttercup rooster varying in age from 1.5-4yrs. How long should I keep them separate from my 12 slw's and partridge rocks? 10 of mine are 12 weeks and 2 are 16 weeks. What is a good introduction strategy? Right now I just have mine in the coop which I will let out tomorrow and I have the "new" chickens in the run. Should I just let them meet outside?
