Last week I lost 4 of my 5 hens to raccoons (I think).....since it's getting cold and a solo chicken is just sad I found some new babies locally yesterday...yay!! They are 3 week old easter eggers and there are 8 of them. How long should I keep them isolated to make sure I'm not introducing any disease or anything to my solo hen? They came from craigslist and the lady said they were npip certified healthy, and they seem fine, but I don't want to do any more damage to my one laying hen! Also I'd be happy to hear any tips on integrating the babies.....the hen I have is just 6 months old and she has never met any new chickens, just her first coop-mates and they were all sent to me together from the hatchery!
