I kindly question this premise...due to so many stories of a flock member being separated for a time due to injury/illness, then being hard to reintegrate back into the flock-attacked as if a 'stranger'. I guess it might depend on how long the separation is/was?Don't worry, they already bonded when being brooded, and other than a brief nod and a peck, they will remember each other and should be fine.
Welcome to BYC @Kate E.
How big are the coop and run, in feet by feet?
Pics would help.
Having a separate enclosure and/or a wire crate or two is IMO an essential tool for chickeneering.
Best of cLuck with your Chicken Juggling!
