Hubby and I would like to add some Australorps to our flock and our local grain store where we usually get chicks from is not getting Lorps this year. How is mypetchicken.com? they don't have a minimum, they have what we want available soon, and the come vaccinated. What do I need to know about mail order chicks?? should I pay the extra for the Marek's vac? Thanks so much!!
