Update.
While no sign of Marek's was found yesterday in my professional assessment, two eye infections were. A third began developing last night.
I have treated MG with the Chinese Skullcap tincture using the 425mg 2X daily dose. From what I'm seeing at the moment, I do not believe it is effective as a prophylactic for MG. I could see a breakthrough case, but 3? At the same time?
I'm looking into the circumstances as all three birds are special needs and stay in the same roost area, I recently changed bedding, two have issues eating, one had a recent eye injury, one recently joined the flock.
Hmmm. Like really recently. (30 days) Like hasn't been here long enough to build up in his system.... He's only ever had the prophylactic dose in his feed.
I may have messed up here. That new one is a Silkie Rooster.
Maybe new birds and special needs birds need boosters.
Hmmm. I'll update. I may have jumped the gun here, but still learned something.
Ah, well...knowledge is power.
