All due to me taking in a flock from a neighbor. I knew I should've quarantined, but my faverolles are in my spare coop. Anyways, should I try to treat or cull? Also, the rooster of the flock was thrown in with the faverolles because he fought with mine. The faverolles and he himself hasn't shown any signs of sickness at all, so would they be safe? I'd be heartbroken to have to cull them all. I've raised them from chicks. However, I don't want to risk anyone else's flocks.
