I plan to integrate newbies to current flock. The hens are 3 years old, 2 Jersey Giants, one Buff Orp and two Wyandotts. The run is a large one. Newbies(2-3 months old) are Polish (3), a Mille Fleur and one Sultan, all hand raised. I know that I need to separate them inside the run with fencing, no problem. What do I need to provide at NIGHT for the newbies until I have introduced them to older girls and the roosts (playhouse in the run)? Should I be worried about the variety of breeds?
