Seeking design advice

This is a story of flock of seven hens living happily and comfortably in their appropriately sized coop and run, and then their owner (me) got greedy and went and acquired new chicks without a plan to house them as they got bigger.

Well, it's not really a story, more of a dilemma. I'll try to post some pics to show my set-up, but it's basically a 3.5' x 4' coop with six nesting boxes, attached to a 8' x 12' covered run. I employ the deep litter method in the run. I close the coop door at night, but otherwise they're in the run most of the day. I do try to give them a little free-range time when I can supervise - on average this comes out to about 30 minutes a day. For the past year, the seven hens have thrived.

So stupid me went out and got two new groups of chickens: 4 eight-week old Swedish Flower Hens and 6 six-week old mixed chicks. The ten young ones are growing quickly and will soon need to be moved from their temporary digs, something which I've not yet planned for. Clearly, my current coop/run can't accommodate 17 chickens.

I have plenty of space, and the first thing I'm considering is fencing a larger area to include the current coop and run - sort of a larger outer run - uncovered but would include some trees which could provide shade and some protection from above. I have a small pre-fab coop and I can get a second (so that's a total of three separate coops) and if I put these in the larger outer run, I could potentially house all 17 in this sort of chicken village. My question is, if 17 hens coexist in this outer area during the day, is it realistic to expect them to all retire to their respective coops every night, or will they all try to squeeze in/fight over the one primary coop?

Option two would be to try to add-on to the existing coop and extend the run so that they could accommodate all 17. Option three would be to build a second covered coop/run in a different part of the property.

Would love any feedback on the three options.

 

The fourth photo shows the current set-up, while the first picture shows part of the greater area (with a prefab coop) that can be fenced in.

 

Okay, thank you, although if I build a new coop it would only be for the 10 new chickens, not for all 17, so that size sounds a little overkill.

I've read about the square-footage per chicken rule-of-thumb. But honestly, the seven in the 3.5x4 have no issues. In fact, they crowd together on the roosting bars at night, leaving unused space on the roosts. There are no signs of stress whatsoever.

But I appreciate your opinion that I should go with option 3. That plan also has some other benefits aside from this.

Does anyone else have a suggestion?

 

Thanks aart. Can you expand on that? In that scenario, I would plan on them staying separate forever, or at least until attrition lowers the overall numbers. Would they have some kind of draw to each other that would cause them to try to escape their pen to get to the other one? What if they're not in the line-of-sight of each other?

 

Okay, that's helpful as that answers my question about creating a type of village with separate coops. But if I build a new coop from scratch, it would go inside a utility yard I have and be completely separate from the other. I think I'm leaning towards option two - expanding the current coop.
