In Ep 17 Dr. Blayne answers the top 5 questions he gets about chicks:
Where does Coccidiosis come from?
What causes pasty butt?
Why are my chicks dyings so young after hatch?
Should I vaccinate my chicks from Marek's Disease?
And why do my chicks have lice or mites?
He lets us know what to worry about (and what we shouldn't) and goes into "mushy chick disease" and how to prevent it.
