I just ordered from Ideal. I only ordered 12. Everything I have read so far has recomended vaccinating, so I checked yes on the Merecks vaccine. But Ideal doesn't recomend it for small flocks. Should I e-mail them and say I changed my mind on the vaccinations? Also after I placed my order I read how they only ship out 1/4 size boxes and that equals 25 chicks and they add extra chicks to make up differance. Does this mean I will get 13 extra roosters, and do the vaccinate the extras too? I am brand new to this. I just don't know.
