It's recommended that you sanitize your coop anytime you add chicks or at least once a year. Virkon S is what I use.

This would be best...along with the testing.What do you mean by depopulating, cleaning and three weeks with no birds?

How many birds are left....IIRC only one?
Just one 2-month-old and three almost a year old.How many birds are left....IIRC only one?
By late fall we expect to have six or seven, and one of our hens has a tendency to go broody so she might hatch two or three next spring. We once had seven older chickens, but three were roosters and one died just before the chicks after being lethargic for three weeks. Now we have three older birds. The sick bird in February had discharge from the eyes and beak and respiratory symptoms.How many chickens total do you expect to keep in your coop/run? How many older chickens did you have and what were the symptoms of the sick bird earlier this year? Respiratory?
Would cleaning and three weeks with no birds mean culling? Is it possible that we could diagnose via testing and treat them in a completely clean, different coop and run while cleaning the other one?
Yes.Would cleaning and three weeks with no birds mean culling? Is it possible that we could diagnose via testing and treat them in a completely clean, different coop and run while cleaning the other one?
Yes.
Diagnosis and treatment might work, but most respiratory stuff never really goes away and symptoms can crop back up with stress. Cross contamination between coops(and your clothes and equipment) would be difficult to avoid.
The risk is up to you.
