I'd give it a couple weeks at least, the longer you can wait the better......I've found patience, observation and not jumping to conclusions very beneficial in learning about chook behavior. They can be curious but don't particularly care for change.
Well, I have good news and bad news. The bad news is we had to get rid of Mary.
The introducing was going horrible with her. The good news is, she has a wonderful new home and is already fitting in. And the introducing between my adult girls and pullets is going AWESOME!
