Adding to flock, quarantine, aggitation

That is in now way big enough for more than 2 birds...especially in your climate.

I have to agree.

According to the usual guidelines, each chicken needs:

• 4 square feet in the coop,
• 10 square feet in the run,
• 1 linear foot of roost,
• 1/4 of a nest box,
• And 1 square foot of permanent, 24/7/365 ventilation, preferably located over the birds' heads when they're sitting on the roost.

4 chickens need:

• 16 square feet in the coop. 4'x4' is the only really practical build for this given the common dimensions of lumber.
• 4 feet of roost
• 40 square feet in the run. 4'x10' or 5'x8'. 6'x6' is a bit too small, 6'x8' is more generous and easier to build than 5'x8'.
• 4 square feet of ventilation. 1, 2'x2' window is theoretically enough but in practice doesn't create any air FLOW so better to spread the venting around (and even better to exceed the minimums, especially in warm climates).
• 2 nest boxes, to give the hens a choice

So that you can see an example, this coop is designed to meet all the minimums for 4 chickens: https://www.backyardchickens.com/articles/the-little-monitor-coop.76275/
