Vaccinating birds at one week

Goodevening everyone,
It good to be here,it quite sometime and work as taken much of my time.
Some weeks ago i vacinate my birds when they clock a week old. I make use of goborro vaccine.

I got that from a vertinary store whichvis alittle bit far from my house thats about 30-40 minutes journey to my place. Most time this is a big place that one can get this vaccines and drugs from.

I got the vaccines and inside the vaccine is an iceblock to keep the vaccine vold till when i get to my destination so that it will not spoil before using it.

I mix the vaccine inside the water and i gave the chicks meanwhile before i went to get drugs i quickly took away the feed and water to that they will be able to drink the vaccine very well.
