I ordered a Marek's disease vaccine ~1.5 months ago, and the backorder date kept getting pushed out.... So I've been calling around, and NOBODY seems to have this! (Jeffers, Randall Burkey, EZ Pet Supply...) AND I HAVE A BATCH OF EGGS IN THE BATOR! Anyone know where I can buy a "stash" of this for a SMALL FLOCK? Will pay for express delivery.... Thanks!
