Nice job!

All of my adult flock was vaccinated at the hatchery - does this pass immunity on to their offspring? If not, does it matter if you vaccinate them when they are older? Is the amount you use the same, regardless of age?

I have five 14 week olds, 9 two week olds, and 4 due to hatch out this Wednesday. They are all offspring of my adult, vaccinated flock.
 
no the vaccination will not pass down to the new offspring. yes you can vaccinate at any age, and it is the same amount regardless of size or age of bird.
