Good afternoon, 

I got 4 pullets about 9 months ago and one of them seems to be showing signs of Marek's disease, so I'm looking for advice about what to do.  She seems to have issues with her legs and has a lot of trouble standing up and walking.  I'm worried if I keep her with the flock that she may transfer the disease to the other three hens.  I also don't want her to suffer unnecessarily.  Any guidance would be much appreciated.

Thank you!
Justin
