How long do I quarantine my coop after potential exposure of infection?

[Allgoodinthecoop]

I recently brought home a rooster to introduce to my small free range flock, as I would any new comer I set him in his own pen (outdoor dog run) and small coop the afternoon I brought him home to settle in and meet everyone the following day. By morning when I was going to introduce him I noticed he has somewhat of a rattle between “bawks” or crows. I immediately took him back to the feed store I purchased him from that morning. He looked as healthy as can be and wasn’t gasping, his comb was bright and gorgeous. My guess is some form of respiratory infection.
My question is, after I clean the coop and the water/feeder how long is that pen contagious? Should I spray anything on the ground (there is no footing, just grass and dirt)? He wasn’t there long, but I’m obviously nervous about the area. This was three days ago and we have had below 30° temperatures at night. I have kept it all closed off from the rest of the flock.

Sorry to hear about this. Did you wash your hands, change your clothes and shoes before going from this rooster to your own chickens? If not, you may have already broken quarantine. If you did all those things there is still a very good chance your chickens were not exposed to whatever this rooster may have had. As for quarantining/ sanitizing the building itself, let me tag an Educator or two for their opinions.

Luckily we were all very diligent about washing hands, I didn’t clean my shoes until the following day after taking him back.

Some respiratory diseases such as MG (mycoplasma gallisepticum) and coryza only are alive about 3 days once the chicken is gone, or on equipment/facilities. Others may last a few weeks, especially in frozen droppings. If you see any signs of illness in the next couple of weeks, it might be good to get some testing. Zoologix and Vetdna (RAL) are labs that will send swabs for private pcr testing. Hopefully, he wasn’t sick, or you quarantined safely.
