I've been reading on this forum for an hour because it looks like my flock has been hit with Marek's too.
I have 7 new pullets ranging in age from a few weeks to 16 weeks. The youngest, a black sex link, is the sick one. I knew something wasn't right with her but couldn't see any symptoms I could report until today. She stumbles around and is holding one wing out now. At first I thought she was being bullied so I put her in a separate cage but still in with the other birds. I realize now this was a big mistake.
I will remove her but it's too late - the others have been exposed. I've read enough to know there is no cure but I would appreciate any info on the best steps I can take to keep the others from getting it (this, too, seems like a crap shoot from what I've read, right?).
This is the first time any of my birds have ever been sick so I'm completely uninformed about what to do. Should I vaccinate the others or is it too late? The little sick bird is eating and drinking and mostly mobile. What is the best I can do for her at this point?
Thanks in advance for any advice.
