Okay, so I know there’s a lot of stuff out there about integrating birds, a ton of different techniques, and that a lot of people adhere to different timelines. I’d love to list my plan below and get feedback from this community, as well as hear what was successful or disastrous for you! We are going to be getting our new chicks sometime in April, so I still have time to make adjustments to my plans 
I currently have 9 girls that will be a year old at the end of March. We will be adding 15 new chickens this year to bring our flock to 24. I am going to try my hand at hatching a dozen fertilized eggs, and then once they hatch run to the farm supply store and buy some hatchery chicks to round out our desired numbers.
We will brood them indoors, in an unused bathroom for 2-4 weeks. Then they will be moved to a small brooding coop outdoors that will still have a heat lamp for a few weeks. The coop will be elevated with access to bare ground underneath, giving the new chickens indoor and outdoor accommodations. Their run will be attached to the side of our existing run. The new chickens and existing flock will be able to see each other and check each other out through the fencing, but will not have direct access to each other.
At about 8 weeks of age, I’m planning to try letting them out to free range together with the adults, under supervision. If a week goes by and there are no problems, I will let them be unsupervised. I am thinking that eventually, they will join up with the existing flock when they are ready and start putting themselves to sleep in the big coop. If there are any problems overnight, I will move the pullets back into their brooding coop until they are a bit bigger... but I am hoping to have the flock integrated by around 10-12 weeks.
Our big run and coop was designed to accommodate 24 chickens so space shouldn’t be an issue. Especially since they free range during the day.
Soooo, what do you guys think? Does it sound like an alright plan? It’s my first time integrating so I will be paying very close attention to the adult chicken behaviors. I am trying to go into this with a flexible mindset, and make the integration as gentle and natural as possible.
