This is my first year of chicken keeping. I had 12 chickens. 7 hens and 5 roosters. We made sure we do nget it from the hatchery and went ahead researched about breeders around us. We found one wich many people reccomended. We got the chickens. Them around 3 months Marek's stroke. Our breeder chose not to vaccinate his chicks as they practice natural farming. We lost 3 hens so far to Marek's it was devastating. We can not "cull" them quickly so it was always a "hospital area in the garage and they die slowly. Now we have number 4 sitting there - . If I knew how devastating it may be - I would choose vaccinations for sure. I talked typ the local vet - he said - vaccinate for Marek for sure with the next ones. I WILL. jUST SEENG MY CHILD BEING SO UPSET OF DYING CHICKS IS HORRIBLE, wE SUPPOSED TO EAT EGGS ALREADY AND INSTEAD WE HAVE this. Just wanted to share our experience - may be someone there will be warned. Can not hear the people out there "protesting " vaccination of our children. Duh! Sorry for venting. My question is - if you went through the similar situation - your advice? Is vaccination going to be enough to protect my next generation of chicks?
