Just vaccinated my chicks for Marek's - totally 50-50 as to who suffered more through the process, me or them (and I used to be a nurse ). Someone posted that, after vaccinating, the chicks appear ill for a bit. How long does that generally last? Is there anything on our part to do to help them through? Also, the disposal instructions for left over vaccine say to burn the vaccine and containers. What do you all do with yours? I mean, I guess I can put it in the garage and burn after the spring thaw - no way I can dig down to the fire pit out back right now! I can't imagine any place saying yes to a request to incinerate my bio-hazard "stuff".
