I've had a heartbreaking outbreak of Marek's in my flock. I've lost 7 young adult hens since March, with 5 of those being in the last 4 weeks--two died this week alone. They all went from being in peak health to dead in 3-4 days, despite all I could do and isolating them immediately.
Anyone else having a Marek's problem right now? I'm wondering if it's a really bad year for it...I've never lost any birds to it in the past. As far as I can tell the disease vector was the youngster wild bird population that hangs out in the yard.
I'm worried for my other young hens who are in the high-risk category, 13 in all. All of the 7 who have died were in the high-risk group. None of the older chickens have shown any symptoms at all.
I know that Marek's is pretty common. This is SO frustrating and sad, I wish I could have done something for these girls. :(
