I'm so sorry
@CapricornFarm. That is the way that it has been going with my Buff Orpingtons. I think I read where SS are almost as susceptible as Buffs when it came to Marek's Disease.
I have one lone SS hen that is almost three years old. She is the sweetest little hen but has had crop problems since she was a three month old pullet. She still has problems on occasions with her crop emptying completely and I have to give her a Dulcolax stool softener to settle things down. I suspected it was because she was a little piggy and would gobble food down like it was her last meal but later read that Marek's can cause crop problems in birds.
Some one on one of the Marek's threads said that it causes so many problems in chickens that after loosing a bird to classical Marek's paralysis they now just automatically says that every time a bird dies, they just categorize it as a Marek's death.
My little SS girl is one of the birds that I keep expecting to keel over but never does. I'm glad. She's a sweet bird, gentle natured and good with the other hens.
Once again, I'm so sorry that you lost another hen plus are still miserable from the flu.
Feel better, please.
