should all the chickens be treated with Tylan 50 Injection? infectious coryza

[TheBeardie]

My newest chicks have symptoms of infectious coryza. Should the whole flock get treated with Tylan 50 Injection. Even the ones not showing symptoms?

From the quick read on these two links, it does look like it can spread fairly quickly. Treatment of the whole flock may be in order. The links also give a bit of info on treatment as well.

I agree - blast the whole lot of 'em. IMO chickens can suffer from illness well before we humble humans notice any symptoms.

Good luck
