I recently relocated my horse to a Grass Farm. It sounded great to have plenty of grass for my horse instead of feeding grain. The winter was OK as BM put roundbales in field to supplement grass not growing.
Come spring the BM asked if each boarder wanted on the lush grass field that might cause colic and/or founder, or on the "Fat field" where not much grass grows. Most boarders elected the "Fat field".
The "Fat field" is actually a dirt/weed lot.
The BM raised the board and lost all but two boarders. Since a 30 days notice is required, the last couple weeks of my notice the remaining horses have had no hay to supplement the lack of grass.
This is a deliberate move by the BM. She is hurting horses she is being paid to care for. Only cares about incoming money and not the wellbeing of the horses.
Beware when boarding at Over the Grass Farm. The trails in The Plains are great, but the BM has no interest in your horses, only her own.
