Hi all, This Spring we had an experience with what I strongly believe was Marek's. I don't have a pathology report and I was quite upset so my husband said no home necropsy. I'm not going to rehash it all but if you're interested here's my post about the chain of events https://www.backyardchickens.com/th...ard-in-progress.1160614/page-12#post-21372950 I've done a ton of reading but what I'm not finding is whether anyone has changed their maintenance routine or made any changes to flock care going forward. Maybe I'm not reading the right threads/posts or doing the right search. I'm wondering if anyone routinely sanitizes their coop, and if so how often? What about supportive care for your birds? Immune enhancing herbs? Do you worm? If so, how often? What about feeders and waterers? I have 12 chicks, almost 5 weeks old and hatched here. No vaccinations and exposed since they were 3 days old. No issues with the littles at this time. All birds positive for sympotims have been put down. Thanks for your help!
