I am reading conflicting information so I decided to just ask. I have a group of 10 wk old girls. They're fully grown and feathered but not of laying age. They're seperated from my older group that consists of 2 Drake's. Is it ok to integrate them all now or should I wait another month or so? They all know each other through a fence. We built a new duck house and I am being impatient getting everyone in there together.
