I am also going to be getting some new Pullets. How long would you recommend keeping them separate? Would it have to be a full month? I'm now very glad that I have two separate coops/runs. At what age would anyone recommend introducing Pullets to an established (but still young) Flock?
Yes, so far, everything I've read recommends a 30 day quarantine. Seems like a hassle, but it's well worth it. It's a very nice thing to have 2 coops to use for this purpose. I'm thinking of looking for another small coop to have around, just in case.
I'm not sure on the ages? Hopefully someone else can chime in for that info.
