Thank you, Cinnamon11!
We have *not yet* brought our 2 new pullets home ... possibly before the end of THIS week.
That will give us time to piece together some sort of temporary quarantine coop in our large shed (currently jam-packed w/ stuff). We'll be clearing some room in there today. It is about 25' away from the main coop, and once the doors are opened for daytime hours, the pullets will get plenty of daylight and some shade, and the older hens and the young pullets will have 'visibility' to each other, but from a distance. And at night, they'll be totally protected from any outside predators, as the shed can be locked.
Then, after 3-4 wks quarantining in the shed pen, I'm hoping that's enough time to then place the pullets *within* the main run, in their separation/enclosed pen, so they'll be closer to the older hens, and hopefully a bit more acclimated to each other's presence by then. Does this sound OK? Thank you again!
