Blending 2 mature flocks

[Baysidegal]

Because of City codes I was forced to move my 4 girls across the street to my neighbors.
Both small flocks are about the same age. We set up a barrier between the two flocks. They can see each other. What is an average time to leave the barrier up?
We just don’t want them to kill each other!

I think it’s 4 weeks maybe

How odd that it's ok across the street, but not at your place.

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.

The houses across the street have deeper lots. City said my coop was too close to dwellings.

That's sad. Chickens in a well-maintained coop cause so much less noise, odor, etc. than equally-well-kept dogs would but people accept dogs and not chickens.

I haven't done adult integration, but what I've read suggests a couple weeks -- until they aren't showing aggression through the wire.

With my chick integration I have been implementing a practice I read about for adult integration -- getting the flock to do flock things together on both sides of the wire.

That is, when I give treats I do it along the fence line so that they eat together. When I put in more pine straw I piled it on both sides of the fence so they were scratching together.
