Adding a mature rooster to an all hen flock

[Ciqala]

How far from the girls should I put his quarantine spot? Should I do any precautionary treatment(s) on him while he's in quarantine?

He would have to be so they aren't breathing the same air, generally, so not within sight. I did mine in the basement bathroom in a wire dog kennel for 5 weeks. And you can dust for lice and mites, but do not give antibiotics! You want symptoms to show up if he's a respiratory disease carrier so you do not add him to your hens at all. Of course, quarantine is not perfect-it will not show if he's a carrier of Marek's Disease, for example.
