we never have used vaccinations with our flock and they are all doing just fine! I have heard of there being strange defects because of the vaccinations so all we do is feed our chicks organic layer feed, and everyone says how they never seen such healthy chickens! Good Luck!
New member from Chick-ago suburbs! We have 4 happy layers about a year old! We gave our Austrolorpe away last week because she was eating eggs! :( She is now managed by a rooster at the 'generals' house and I understand she is cured. We are happy with the 4 and hope they didn't pick up her bad...
