Introduce two new hens to my three hen flock

[ChickEngineer]

I have three hens two years old, one RR and two AC's. Not getting enough eggs so would like to add two more girls (city limit).
The RR is a bit of a bully so was thinking of pullets not chicks. I can make something temporary next to the coop for the new girls. How long before they could be put together?

Hens can be put together straight away, it just depends on how friendly they are to each other.
It's good that you have decided on keeping pullets instead of chicks. I doubt the chicks would ever be fully accepted by the older ones.
There is no real answer for your question because it depends on how friendly the older hens are to the pullets.. You can start by making them eat close together so they have contact with each other without fighting. Once they are getting along fine with each other, then you can put them in with the three older hens.

The time I recommend is a week, but longer can help. After that, letting them mingle for a week or more before actually putting them in the same coop, also is good. The more space they have the easier it goes.
