I would definitely speak to the breeder about what they have already done. Depending on what was done up till you get her will depend on what you need to do. I don't want to tell you things to do if the breeder had already done them.
I agree..once you know what the breeders done, then we can let you know if she needs anything else..So happy for you!!!
But here is a list of a few things I would have on hand
Baycox for cocci (order from horseprerace.com) Or choose OTC sulmet or Dimethox
C D Antitoxin
Antibioitc (tylan 200 for OTC or Nuflor for RX)
quality loose mineral
