Please i need a reply urgently. My birds are just 5 days old and i bought lasota yesterday to administer to them in two days time. Pieces of ice block was use to package it for me at the shop, and on getting home, i kept it under the freezer with the ice. And now, it is frozen. Please can i still use it? How do i know if the vaccine is not dead yet? Thanks in anticipation. - Founder Jef ...
