How is she doing? Have you been weighing her. It seems that her BM's are getting less green which is good. Did I already suggest a bit of milk thistle? That last, really orangy green one may have just been from the B vitamins. It had that bright, artificial, neon green color rather than a deep liver enzyme green. The mareks vaccine only costs $25 with shipping from Jeffers. I have read a study (and I have to find it again) that suggested that you can vaccinate an older flock and expect protection or a less severe outbreak even if they have already been exposed to the virus. I believe the study or studies that I read also suggested some benefit in vaccinating a bird that is already symptomatic. Birds expose to Mareks usually can become symptomatic starting at about 5 weeks and I can't remember what the cutoff age is but that's just an average. Birds can actually become symptomatic at any age.
