House move and Myco

Hi, as some of you know i lost the 3 chooks i bought in with Myco symptoms [ with vet treatment]. None of the others have shown any signs , although i suppose they could be carriers. Our house move will be in a few weeks, i will make sure everything is ready the other end , but should i put them on antibiotics[in water] or just give a tonic , then see if any of the others have picked it up, thoughts please as i'm not sure whats best
    Have a feeling i should be in the Hen House, sorry

Personally I wouldn't use A/B without an outbreak of illness to treat.  A/Bs should be treated with respect and not used indiscriminately.  Using an inappropriate A/B can make matters worse. and why destroy the chx digestive system microflora for no good reason.

Regards
