I just heard back from the vet - my chicken has Mercks. What I wonder now is what do I do with the rest of the flock? The other three chickens have been exposed so I am wondering what I should do. Here are the options I know of thus far: 1) Wash and scrub everything on a regular basis! Use a bleach-water solution on the soil and watch them closely. 2) Cull the flock. Other information: the chickens are in a temporary coop while I build them one that is more sturdy. Will putting chickens in this permanent coop contaminate it for future flocks? Thank you, thank you for any help.
