B complex dosage

[my beautiful girls]

@Eggcessive could I ask a question? My 3.5 year old blue australorp, ophelia. Has infectious bronchitis, probably marecks because 2 of my pullets passed 5 months and 1 month before ophelia became very sick. Last October when she molted her balance was off, now this October same, but she's not molting. It's only been 2 days since she has been given 1/4 tab of b complex and 400iu of vitamin e. She has a respiratory infection, tomorrow is last dose of baytril. That is getting better, but balance is not.
My question is can I give her a half tab of b complex for a week or so to help jump start, what I think is a vitamin deficiency? If I'm wrong, it's marecks and I don't want to focus on that.
I love her dearly. I appreciate your advice.

You can give 1/2tablet B-Complex for a week if you wish, any excess will be excreted in the urine.
