Diamond B Farm was designed by the Broks to offer the best facilities and care for broodmares and foals:

  • The main barn, which was recently built, offers stalls that are bright and airy and bedded deeply with straw
  • The bank barn, which is just outside the Brok’s home, features five heated foaling stalls that are monitored by CCTV
  • Diamond B’s staff of horsemen is housed on-site
  • Foaling season is a busy time for Becky Brok as she is involved with every foaling.
