No reason to freak out. Sorry.I'm freaked out.

Actually the amprolium doesn't block thiamine but mimics it to slow the growth of and help starve out the coccidia since that is what they feed on, while the chicks can build better immunity.
Medicated feed might be the right choice for YOU!

Sounds like you have made some changes with the early introduction of dirt and all and are doing everything you can to avoid any repeats of that awful incident.

Please be aware that even using medicated feed SOMETIMES isn't enough. So if you do start to see any symptoms that give you cause for concern, just don't let it give you any false sense of security.. meaning it CAN still happen and you might still need to treat. Some people face special circumstances regarding stock load, weather, pasture conditions or so on.
Good luck for a doting mum!
