I have reached a point where I need input from those of you who are also facing this problem. I have 4 Marek's hens left and one is suffering from severe prolapse and her keel bone is extremely prominent. These girls eat as if there's no tomorrow and will never be anything except what they are due to the disease. I have some of their offspring hatched and at the 4 month age. One roo from this group just died a few days ago showing the leg paralysis and constant eating. No cocci, no respiratory issues, happy until he was no more. The others in this group are normal sized and very healthy so I guess there is merit to raising for immunity. I guess what I need to know is if it is worth it in the end, or should I just say goodbye and cull the poor girls left. I know this has to be a personal choice but I would really like some input. It would be easy to cull the ones affected, but then what? Replace them? Okay, but how long do they have to stay apart even if they're vaccinated for Marek's? 6 months? A year? What about my original flock of layers and roo? They will be 2 years old in April. Do they go as well? They never had any symptoms of Marek's, but have been living with these survivors for months now. A lot of questions that I hope some of you can help me work through.
