So whenever you get chickens they will establish a pecking order. They will quibble / quarrel / and sometimes outright fight until this is established. Sometimes it can take a month or more I am told 
With that, lets say you had an established flock, and remove one for a while, then re introduce her. Is the pecking order kind of 'remembered' or do they have to go through ALL that again? If it's remembered, for how long. If you remove her for a day, then yah they probably are not going to revert, if you remove her for a month? Will that kick off a new 'pecking order assembly to the chicken thunderdome'? What is around the threshold time to have a reintroduce be seen like a totally new bird? or do they always remember sort of?
