Corid Egg Withdrawal Time For Hatching Eggs?

[CMLR]

Does anyone know if it is safe to hatch eggs when the hen is on Corid? My gut says no, that the thiamine blocking properties may result in chick vitamin deficiencies. But this I a guess and I am not sure how long you would need to wait after administering the Corid treatment. Thanks!
