I hope so too. I don't know much about Marek's, but this spring her pupil started closing down. There was never any discoloration in the eye and she acted normally all the time, even yesterday. She died in her sleep and was found on the coop floor this morning.
Buried an Ocular Marek's victim. :( (At least I think that's what it is.) The rest of them were having fun scratching in the freshly mown lawn and getting some of the abundant ants.
