Introducing new chickens

[Ruggergirl29]

How do I get my new chickens I have two of them that are almost two months old to live in the same coop as my five four month old chickens.They were kept separate so that they wouldn’t get attacked until they got older but they are getting to big to live inside now.My four month old chickens always attack them when we put the two new chickens in with them.How do I get them all to get along in the coop and live together.My Araucanian leg bar chicken makes a screeching noise and then attacks them ever time they are around.

How long have they been able to see but not touch each other?

Photos of your set up? How big is the coop and run?

Handful of times probably isn't enough. I'd try see but not touch outside of the coop for at least a week, and then some supervised time together without any fencing separating them. If they seem pretty ok with each other at that point, try the coop again, though optimally you'll want to provide a separate roost for the younger birds, or possibly a fenced off area for a few days just to ensure the younger birds are safe.

HOw big's the coop?

Yes, dimensions and pics of your coop would help immensely here.

Here's some tips about.....
Integration Basics:
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.
Good ideas for hiding places:
