I think I read somewhere...
And I looked for a while before I posted this.....
That denagard prevents transmission of MG through eggs....so if you had infected hens you could treat them and collect the eggs for hatching and the resulting chicks would not have MG. Is this true or did I imagine it?
I have new chicks hatching now.....I going to vaccinate them along with my other birds....what will happen if I give the vaccine to an older bird that had been exposed?
