Mycoplasma maternal antibody titre in day old chicks

I would be grateful if somebody can explain why mycoplasma maternal antibody titre is always negative in day-old chick from vaccinated parent breeder when tested by Elisa? Why do day-old chicks tested for mycoplasma maternal antibody at 3 week old with Elisa and why does that happen with mycoplasma and not another respiratory disease?

Firstly: the MDA transfer from hen to DOC very low for MD. I see some technical around 20% or something while IBD, ND, IB the percent is higher (70%).
Second: what kind of vaccine are you using? Kill or live?
