Chicken sick, not laying, probably Mareks

[chickengirl1990]

I'm updating this thread Serenity Sprouts still has Marek's circulating. I had a hen die from it in December 2025. It was a confirmed Marek's case by a local vet and she was vaccinated as a chick so the vaccination is not 100 percent effective. She was a sweet Blue Copper Maran. I have been really disappointed as I've bought 7 chicks from them and now had 2 die in less than 6 months. I just purchased an incubator so guess I'll be learning how to hatch my own eggs this season.
