Introducing new members

[Chickletmomma]

I will be getting possibly 3 new hens added to my flock and removing 2 roos. They are all about 8 weeks old. I will have to hold the 2 roos for the weekend until my sister leaves town. Will everyone be ok? Should I separate or just let them work it out? My hens still chirp but 3 of my 5 roos crow. The 3 that are crowing are all bantams and my standard roos haven't started crowing yet. I just dont want a big fight and someone getting hurt. Thanks I advance

Do not just add 3 new birds without first reading this article

Not quite sure what the bolded above means.
Is she taking them?

FYI.....semantics, maybe, but can be important communication terms when discussing chicken behavior.
Female chickens are called pullets until one year of age, then they are called hens.
Male chickens are called cockerels until one year of age, then they are called cocks(or cockbirds or roosters).

So you are keeping 3 cockerels?
How many pullets do you have?
Do you have other older birds or is this your first flock?
Knowing more about your goals and the housing you have would garner more specific advice.

Integration can be tricky.
It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.

In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can really help. Lots of diversion and places to 'hide' instead of bare wide open run.

This is good place to start reading, tho some info is outdated IMO:
