I have 12 fledglings all from the same hatchery. I found someone on Craigslist with frizzle x silkie fledglings and I have to have them so I am picking up the three chicks on Friday. I need to know though, is this a bad idea? She sounds like she just breeds by accident/for fun. I think hatchery chicks are vaccinated and these chicks will not be. Is there anything special I need to do? Should I quarantine them for a while, if so how long? Thanks.
