I'd like to get some fertile eggs in the spring for my silkie to hatch and raise. We have no roo. But how does one get just a few chicks vaccinated? My silkie has never raised babies and goes broody. She's needing to be a momma. I'll most likely get her a few chicks already vaccinated and slip them under her...not as much fun, but still cute and good for her. How do you all get baby chicks vaccinated?!
